2. Random-access memory - Wikipedia

   en.wikipedia.org/wiki/Random-access_memory

   The memory cell is the fundamental building block of computer memory. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). Its value is maintained/stored until it is changed by the set/reset process.

3. DDR4 SDRAM - Wikipedia

   en.wikipedia.org/wiki/DDR4_SDRAM

   DDR4 is not compatible with any earlier type of random-access memory (RAM) due to different signaling voltage and physical interface, besides other factors. DDR4 SDRAM was released to the public market in Q2 2014, focusing on ECC memory , [ 6 ] while the non-ECC DDR4 modules became available in Q3 2014, accompanying the launch of Haswell-E ...

4. Semiconductor memory - Wikipedia

   en.wikipedia.org/wiki/Semiconductor_memory

   All semiconductor memory, not just RAM, has the property of random access. DRAM (Dynamic random-access memory) – This uses memory cells consisting of one MOSFET (MOS field-effect transistor) and one MOS capacitor to store each bit. This type of RAM is the cheapest and highest in density, so it is used for the main memory in computers.

7. High Bandwidth Memory - Wikipedia

   en.wikipedia.org/wiki/High_Bandwidth_Memory

   High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...
