PC100 Synchronous Dynamic Random Access Memory (PC100 SDRAM)

Part of the Storage hardware glossary:

Also see RAM types .

PC100 SDRAM is synchronous DRAM ( Synchronous dynamic random access memory ) that states that it meets the PC100 specification from Intel. Intel created the specification to enable RAM manufacturers to make chips that would work with Intel's i440BX processor chipset. The i440BX was designed to achieve a 100 MHz system bus speed. Ideally, PC100 SDRAM would work at the 100 MHz speed, using a 4-1-1-1 access cycle. It's reported that PC100 SDRAM will improve performance by 10-15% in an Intel Socket 7 system (but not in a Pentium II because its L2 cache speed runs at only half of processor speed).
