==={{anchor|EMBEDDED}}Embedded use===
Many categories of industrial and scientific subsystems, automotive electronics, and similar [[embedded system]]s, contain SRAM which, in this context, may be referred to as ''embedded SRAM'' (ESRAM).<ref>{{cite web |url=https://wccftech.com/microsoft-xbox-esram-huge-win-explains-reaching-1080p60-fps/ |title=Microsoft Says Xbox One's ESRAM is a "Huge Win" – Explains How it Allows Reaching 1080p/60 FPS |author=Fahad Arif |date=Apr 5, 2014 |access-date=2020-03-24}}</ref> Some amount is also embedded in practically all modern appliances, toys, etc. that implement an electronic user interface.

SRAM in its [[dual-ported RAM|dual-ported]] form is sometimes used for real-time [[digital signal processing]] circuits.<ref>{{citation |title=Shared Memory Interface with the TMS320C54x DSP |url=https://www.ti.com/lit/an/spra441/spra441.pdf |access-date=2019-05-04}}</ref>

===In computers===
SRAM is used in personal computers, workstations and peripheral equipment: CPU [[register file]]s, internal [[CPU cache]]s and [[GPU cache]]s, [[hard disk]] buffers, etc. [[LCD screen]]s also may employ SRAM to hold the image displayed. SRAM was used for the main memory of many early personal computers such as the [[ZX80]], [[TRS-80 Model 100]], and [[VIC-20]].<!--[[User:Kvng/RTH]]-->

Some early [[memory card]]s in the late 1980s to early 1990s used SRAM as a storage medium, which required a lithium battery to keep the contents of the SRAM.<ref name="auto1">{{Cite magazine |first=Nick |last=Stam |url=https://books.google.com/books?id=x2Fa5SDi0G8C&dq=memory+cards+SRAM+battery&pg=PA270 |title=PCMCIA's System Architecture |magazine=PC Mag |date=December 21, 1993 |publisher=Ziff Davis, Inc. |via=Google Books}}</ref><ref>{{Cite magazine|url=https://books.google.com/books?id=-Xr7Ic-ivyMC&dq=atari+portfolio+memory+card&pg=PT318 |first=Jonathan |last=Matzkin |title=$399 Atari Portfolio Takes on Hand-held Poqet PC |magazine=PC Mag |date=December 26, 1989|publisher=Ziff Davis, Inc. |via=Google Books}}</ref>

=== Integrated on chip ===
SRAM may be integrated on chip for:

* the RAM in [[microcontrollers]] (usually from around 32&nbsp;bytes to a [[megabyte]]),
* the on-chip [[CPU cache|caches]] in more powerful CPUs, such as the [[x86]] family, and many others (from 8&nbsp;[[kilobyte|KB]], up to many megabytes),
* the registers and parts of the state-machines used in some microprocessors (see [[register file]]),
* [[scratchpad memory]],
* [[application-specific integrated circuit]]s (ASICs) (usually in the order of kilobytes),
* and in [[field-programmable gate array]]s (FPGAs) and [[complex programmable logic device]]s (CPLDs).

===Hobbyists===
Hobbyists, specifically home-built processor enthusiasts,<ref>{{Cite web|url=https://3.14.by/en/read/homemade-cpus|title=Homemade CPU – from scratch : Svarichevsky Mikhail|website=3.14.by}}</ref> often prefer SRAM due to the ease of interfacing. It is much easier to work with than DRAM as there are no refresh cycles and the address and data buses are often directly accessible.{{Citation needed|date=May 2024}} In addition to buses and power connections, SRAM usually requires only three controls: Chip Enable (CE), Write Enable (WE) and Output Enable (OE). In synchronous SRAM, Clock (CLK) is also included.<ref>{{cite web |url=https://www.eeherald.com/section/design-guide/esmod15.html |title=Embedded Systems Course- module 15: SRAM memory interface to microcontroller in embedded systems |access-date=2024-04-12}}</ref>
