picture info	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 ...

	Computational RAM Computational RAM (C-RAM) is random-access memory with central processing unit, processing elements integrated on the same chip. This enables C-RAM to be used as a SIMD computer. It also can be used to more efficiently use memory bandwidth within a memory chip. Overview The most influential implementations of computational RAM came from The Berkeley IRAM Project. Vector IRAM (V-IRAM) combines DRAM with a vector processor integrated on the same chip. Christoforos E. Kozyrakis, Stylianos Perissakis, David Patterson, Thomas Anderson, et al"Scalable Processors in the Billion-Transistor Era: IRAM" IEEE Computer (magazine). 1997. says "Vector IRAM ... can operate as a parallel built-in self-test engine for the memory array, significantly reducing the DRAM testing time and the associated cost." Reconfigurable Architecture DRAM (RADram) is DRAM with reconfigurable computing FPGA logic elements integrated on the same chip. Mark Oskin, Frederic T. Chong, and Timothy Sherwood"Active Pages: ...
