2. Random-access memory - Wikipedia

   en.wikipedia.org/wiki/Random-access_memory

   GDDR (graphics DDR) is a form of DDR SGRAM (synchronous graphics RAM), which was first released by Samsung as a 16 Mbit memory chip in 1998. Types. The two widely used forms of modern RAM are static RAM (SRAM) and dynamic RAM (DRAM). In SRAM, a bit of data is stored using the state of a six-transistor memory cell, typically using six MOSFETs ...

3. Computer memory - Wikipedia

   en.wikipedia.org/wiki/Computer_memory

   Computer memory stores information, such as data and programs, for immediate use in the computer. [2] The term memory is often synonymous with the terms RAM, main memory, or primary storage. Archaic synonyms for main memory include core (for magnetic core memory) and store. [3]

4. Semiconductor memory - Wikipedia

   en.wikipedia.org/wiki/Semiconductor_memory

   There are numerous different types using different semiconductor technologies. The two main types of random-access memory (RAM) are static RAM (SRAM), which uses several transistors per memory cell, and dynamic RAM (DRAM), which uses a transistor and a MOS capacitor per cell.

5. Memory cell (computing) - Wikipedia

   en.wikipedia.org/wiki/Memory_cell_(computing)

   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.

6. Dynamic random-access memory - Wikipedia

   en.wikipedia.org/wiki/Dynamic_random-access_memory

   Dynamic random-access memory ( dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...

7. Non-volatile memory - Wikipedia

   en.wikipedia.org/wiki/Non-volatile_memory

   Non-volatile memory ( NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data. Non-volatile memory typically refers to storage in semiconductor memory chips, which store data in floating-gate memory cells ...
