2. Phase-change memory - Wikipedia

   en.wikipedia.org/wiki/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 .

3. DDR4 SDRAM - Wikipedia

   en.wikipedia.org/wiki/DDR4_SDRAM

   DDR4 memory is supplied in 288-pin dual in-line memory modules (DIMMs), similar in size to 240-pin DDR3 DIMMs. DDR4 RAM modules feature pins that are spaced more closely at 0.85 mm compared to the 1.0 mm spacing in DDR3, allowing for a higher pin density within the same standard DIMM length of 133.35 mm (5¼ inches).

   Modules are instead designed to run at different clock frequencies: for example, a PC-1600 module is designed to run at 100 MHz, and a PC-2100 is designed to run at 133 MHz. A module's clock speed designates the data rate at which it is guaranteed to perform, hence it is guaranteed to run at lower ( underclocking ) and can possibly run at ...

   Possible practical application of the MRAM includes virtually every device that has some type of memory inside such as aerospace and military systems, digital cameras, notebooks, smart cards, mobile telephones, cellular base stations, personal computers, battery-backed SRAM replacement, datalogging specialty memories (black box solutions ...

6. 3D XPoint - Wikipedia

   en.wikipedia.org/wiki/3D_XPoint

   Development of 3D XPoint began around 2012. [8] Intel and Micron had developed other non-volatile phase-change memory (PCM) technologies previously; [note 1] Mark Durcan of Micron said 3D XPoint architecture differs from previous offerings of PCM, and uses chalcogenide materials for both selector and storage parts of the memory cell that are faster and more stable than traditional PCM ...

7. Static random-access memory - Wikipedia

   en.wikipedia.org/wiki/Static_random-access_memory

   SRAM is also used in personal computers, workstations, routers and peripheral equipment: CPU register files, internal CPU caches, internal GPU caches and external burst mode SRAM caches, hard disk buffers, router buffers, etc. LCD screens and printers also normally employ SRAM to hold the image displayed (or to be printed). LCDs can have SRAM ...
