What is a Single Inline Memory Module (SIMM)?

What does SIMM stand for?

Single inline Memory Module (SIMM) is a type of RAM (Random Access reminiscence) that was famous within the early Nineteen Eighties to overdue Nineteen Nineties. SIMMs have 32-Bit facts paths and were standardized underneath the JEDEC JESD-21C general. Non-IBM PC Computer Systems, Unix Workstations and the Mac IIfx used the non-trendy SIMMS.

What Does Single Inline Memory Module Mean?

Wang Laboratories invented and Patented the SIMM in 1983. SIMMs with 30-pin variations have been utilized in 386, 486, Macintosh Plus, Macintosh II, Quadra and Wang VS sySTEMs. The 72-pin variant became used in IBM PS/2, 486, Pentium, Pentium Pro and some Pentium II systems.

Dual inline memory module (DIMM) has cHanged SIMM beginning with the Intel P-five Pentium Processors. SIMMs have redundant contacts on both facets of the module, while DIMMS have separate electric contacts on each side. DIMMS have 64-bit Records paths, instead of SIMMS which had 32-bit inFormation paths. Intel Pentiums required that SIMMs be installed in pairs and DIMMs removed that requirement.
