English: Circuit diagram of an SRAM cell, built with four MOSFETs and two resisitors. The bulk connection of all transistors is to ground, but is not shown from simplicity. The bulk connection of all transistors is to ground, but is not shown from simplicity.

In addition to 6T SRAM, other kinds of SRAM use 4, 5, 7, [21] 8, 9, [20] 10 [22] (4T, 5T, 7T 8T, 9T, 10T SRAM), or more transistors per bit. [ 23 ] [ 24 ] [ 25 ] Four-transistor SRAM is quite common in stand-alone SRAM devices (as opposed to SRAM used for CPU caches), implemented in special processes with an extra layer of polysilicon ...
TSMC began risk production of 256 Mbit SRAM memory chips using a 7 nm process in April 2017. [125] Samsung and TSMC began mass production of 7 nm devices in 2018. [126] Apple A12 and Huawei Kirin 980 mobile processors, both released in 2018, use 7 nm chips manufactured by TSMC. [127]
On August 18, 2008, AMD, Freescale, IBM, STMicroelectronics, Toshiba, and the College of Nanoscale Science and Engineering (CNSE) announced that they jointly developed and manufactured a 22 nm SRAM cell, built on a traditional six-transistor design on a 300 mm wafer, which had a memory cell size of just 0.1 μm 2.

A pair of Saturday NFL games drew a larger viewing audience than college football for the rollout of the sport's 12-team playoff. The playoff game between SMU and Penn State averaged 6.4 million ...
SRAM became an alternative to magnetic-core memory, but required six MOS transistors for each bit of data. [21] Commercial use of SRAM began in 1965, when IBM introduced their SP95 SRAM chip for the System/360 Model 95. [9] Toshiba introduced bipolar DRAM memory cells for its Toscal BC-1411 electronic calculator in 1965.
