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.

English: Circuit diagram of an SRAM cell, built with six MOSFETs. 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.
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]
Two additional access transistors serve to control the access to a storage cell during read and write operations. 6T SRAM is the most common kind of SRAM. [20] 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.
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.
The NFL's six wild-card games feature some potentially entertaining affairs – and maybe a few duds along the way to boot.
1T-SRAM is a pseudo-static random-access memory (PSRAM) technology introduced by MoSys, Inc. in September 1998, which offers a high-density alternative to traditional static random-access memory (SRAM) in embedded memory applications.
Kansas City Chiefs star tight end Travis Kelce had a message for fans ahead of their AFC Divisional Round playoff game against the Houston Texans.
