Editing Static random-access memory (section)

===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>
