The Machine (computer Architecture)
The Machine is the name of an experimental computer made by Hewlett-Packard, Hewlett Packard. It was created as part of a research project to develop a new type of computer architecture for servers. The design focused on a “memory centric computing” architecture, where Non-volatile random-access memory, NVRAM replaced traditional DRAM and disks in the memory hierarchy. The NVRAM was Byte-addressable, byte addressable and could be accessed from any CPU via a Photonic integrated circuit, photonic Interconnect (integrated circuits), interconnect. The aim of the project was to build and evaluate this new design. Hardware overview The Machine was a computer cluster with many individual nodes connected over a memory fabric. The fabric interconnect used Vertical-cavity surface-emitting laser, VCSEL-based silicon photonics with a custom chip called the X1. Access to memory is Non-uniform memory access, non-uniform and may include multiple Hop (networking), hops. The Machine was env ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally esta ...

Gen-Z (consortium)
The Gen-Z Consortium is a trade group of technology vendors involved in designing CPUs, random access memory, servers, storage, and accelerators. The goal was to design an open and royalty-free "memory-semantic" bus protocol, which is not limited by the memory controller of a CPU, to be used in either a switched fabric or a point-to-point device link on a standard connector. In November 2021, the GenZ Consortium voted to transfer all its specifications and intellectual property to the CXL Consortium. History The consortium was publicly announced on October 11, 2016. Members include server vendors Cisco Systems, Cray, Dell Technologies, Hewlett Packard Enterprise, Huawei, IBM, and Lenovo. CPU vendor members include Advanced Micro Devices, ARM Holdings, Broadcom Limited, IBM, and Marvell. Memory and storage vendor members include Micron Technology, Samsung, Seagate Technology, SK Hynix, and Western Digital. Other members include IDT Corporation, IntelliProp, Mellanox Techn ...

Resistive Random-access Memory
Resistive random-access memory (ReRAM or RRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a dielectric solid-state material, often referred to as a memristor. ReRAM bears some similarities to conductive-bridging RAM (CBRAM) and phase-change memory (PCM). CBRAM involves one electrode providing ions that dissolve readily in an electrolyte material, while PCM involves generating sufficient Joule heating to effect amorphous-to-crystalline or crystalline-to-amorphous phase changes. By contrast, ReRAM involves generating defects in a thin oxide layer, known as oxygen vacancies (oxide bond locations where the oxygen has been removed), which can subsequently charge and drift under an electric field. The motion of oxygen ions and vacancies in the oxide would be analogous to the motion of electrons and holes in a semiconductor. Although ReRAM was initially seen as a replacement technology for flash memory, the cost an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SanDisk
SanDisk is a brand for flash memory products, including memory cards and readers, USB flash drives, solid-state drives, and digital audio players, manufactured and marketed by Western Digital. The original company, SanDisk Corporation was acquired by Western Digital in 2016. Western Digital was the fourth-largest manufacturer of flash memory having declined from third-largest in 2014. History SanDisk was founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan, incorporated at the time as SunDisk. SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage. In 1991 SanDisk produced the first flash-based solid-state drive (SSD) in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1,000. In 1992, SanDisk (then SunDisk) introduced FlashDisk, a series of memory cards made for the PCMCIA or PC card form factor, so they could be inserted int ...

Memristor
A memristor (; a portmanteau of ''memory resistor'') is a non-linear two-terminal electrical component relating electric charge and magnetic flux linkage. It was described and named in 1971 by Leon Chua, completing a theoretical quartet of fundamental electrical components which comprises also the resistor, capacitor and inductor. Chua and Kang later generalized the concept to memristive systems. Such a system comprises a circuit, of multiple conventional components, which mimics key properties of the ideal memristor component and is also commonly referred to as a memristor. Several such memristor system technologies have been developed, notably ReRAM. The identification of memristive properties in electronic devices has attracted controversy. Experimentally, the ideal memristor has yet to be demonstrated. As a fundamental electrical component Chua in his 1971 paper identified a theoretical symmetry between the non-linear resistor (voltage vs. current), non-linear capacit ...

NVDIMM
A NVDIMM (pronounced "en-vee-dimm") or non-volatile DIMM is a type of persistent random-access memory for computers using widely used DIMM form-factors. Non-volatile memory is memory that retains its contents even when electrical power is removed, for example from an unexpected power loss, system crash, or normal shutdown. Properly used, NVDIMMs can improve application performance and system crash recovery time. They enhance solid-state drive (SSD) endurance and reliability. Many "non-volatile" products use volatile memory during normal operation and dump the contents into non-volatile memory if the power fails, using an on-board backup power source. Volatile memory is faster than non-volatile; it is byte-addressable; and it can be written to arbitrarily, without concerns about wear and device lifespan. However, including a second memory to achieve non-volatility (and the on-board backup power source) increases the product cost compared to volatile memory. There are many emerging n ...

Phase-change Memory
Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, OUM (ovonic unified memory) and C-RAM or CRAM (chalcogenide RAM)) is a type of non-volatile random-access memory. PRAMs exploit the unique behaviour of chalcogenide glass. In PCM, heat produced by the passage of an electric current through a heating element generally made of titanium nitride is used to either quickly heat and quench the glass, making it amorphous, or to hold it in its crystallization temperature range for some time, thereby switching it to a crystalline state. PCM also has the ability to achieve a number of distinct intermediary states, thereby having the ability to hold multiple bits in a single cell, but the difficulties in programming cells in this way has prevented these capabilities from being implemented in other technologies (most notably flash memory) with the same capability. Recent research on PCM has been directed towards attempting to find viable material alternatives to the phase-change materi ...
