Short for Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU''s bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing EDO DRAM in many newer computers.

The Module is SDRAM PC133 CL3 Small Outline Memory module. The Module density from 64MB to 512MB, it consists SDRAM PC133 Synchronous DRAMs, Memory Module intented for mounting into 144-pin edge connector sockets.
