SRAM exhibits data remanence, [1] but it is still volatile in the conventional sense that data is eventually lost when the memory is not powered. The term static differentiates SRAM

Question
[default - edit me]
Answer

The power consumption of SRAM varies widely depending on how frequently it is accessed; in some instances, it can use as much power as dynamic RAM, when used at high frequencies, and some ICs can consume many watts at full bandwidth. On the other hand, static RAM used at a somewhat slower pace, such as in applications with moderately clocked microprocessors, draws very little power and can have a nearly negligible power consumption when sitting idle – in the region of a few micro-watts. Several techniques have been proposed to manage power consumption of SRAM-based memory structures.[2]

SRAM is also used in personal computers, workstations, routers and peripheral equipment: CPU register files, internal CPU caches and external burst mode SRAM caches, hard disk buffers, router buffers, etc.

eral megabytes may be used in complex products such as digital cameras, cell phones, synthesizers, etc. SRAM in its dual-ported form is sometimes used for realtime digital signal processing circuits. [citation needed] In computers[edit] <span>SRAM is also used in personal computers, workstations, routers and peripheral equipment: CPU register files, internal CPU caches and external burst mode SRAM caches, hard disk buffers, router buffers, etc. LCD screens and printers also normally employ static RAM to hold the image displayed (or to be printed). Static RAM was used for the main memory of some early personal computers such as
