DDR SDRAMDouble data rate synchronous dynamic random-access memory (DDR SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) widely used in computers and other electronic devices. It improves on earlier SDRAM technology by transferring data on both the rising and falling edges of the clock signal, effectively doubling the data rate without increasing the clock frequency.
Samsung ElectronicsSouth Korean multinational electronics corporationSamsung Electronics Co., Ltd. (SEC; stylized as SΛMSUNG; Korean: 삼성전자) is a South Korean multinational consumer electronics and semiconductor corporation founded in 1969 and headquartered in Yeongtong District, Suwon, South Korea. It is the flagship listed company of the Samsungchaebol and a major supplier of memory chips, displays, smartphones and home appliances.
Clock signalIn electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) is an electronic logic signal (voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits.
Memory bankA memory bank is a logical unit of storage in electronics, which is hardware-dependent. In a computer, the memory bank may be determined by the memory controller along with physical organization of the hardware memory slots. In a typical synchronous dynamic random-access memory (SDRAM) or double data rate SDRAM (DDR SDRAM), a bank consists of multiple rows and columns of storage units, and is usually spread out across several chips.
Double data rateIn computing, double data rate (DDR) describes a computer bus that transfers data on both the rising and falling edges of the clock signal and hence doubles the memory bandwidth by transferring data twice per clock cycle. This is also known as double pumped, dual-pumped, and double transition. The term toggle mode is used in the context of NAND flash memory.SamsungSouth Korean multinational conglomerateSamsung Group (Korean: 삼성; pronounced; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in the Samsung Town office complex in Seoul. The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest chaebol (family-controlled conglomerates in South Korea). As of 2024, Samsung has the world's fifth-highest brand value.
Dynamic random-access memoryDynamic random-access memory (dynamic RAM or DRAM) is a type of random-accesssemiconductor memory that stores each bit of data in a memory cell. A DRAM memory cell usually consists of a microscopic capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor, some only use two transistors.
Interleaved memoryIn computing, interleaved memory is a design which compensates for the relatively slow speed of dynamic random-access memory (DRAM) or core memory, by spreading memory addresses evenly across memory banks. That way, contiguous memory reads and writes use each memory bank in turn, resulting in higher memory throughput due to reduced waiting for memory banks to become ready for the operations.JEDECThe Joint Electron Device Engineering Council (JEDEC) Solid State Technology Association is a consortium of the semiconductor industry headquartered in Arlington, United States. It has over 300 members and is focused on standardization of part numbers, defining an electrostatic discharge (ESD) standard, and leadership in the lead-free manufacturing transition.
Pipeline (computing)Data processing chain In computing, a pipeline, also known as a data pipeline, is a set of data processing elements connected in series, where the output of one element is the input of the next one. The elements of a pipeline are often executed in parallel or in time-sliced fashion. Some amount of buffer storage is often inserted between elements. Concept and motivation Pipelining is a commonly used concept in everyday life.
Finite-state machineIn theoretical computer science, a finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some inputs; the change from one state to another is called a transition.
