Memory Module Specification
DESCRIPTION:
ValueRAM's KVR333X64C25K2/512 is a kit of two 32M x 64-bit (256MB) DDR333 CL2.5
SDRAM (Synchronous DRAM) memory modules. Total kit capacity is 512MB. The
components on each module include nine 32M x 8-bit (8M x 8-bit x 4 Bank) DDR333
SDRAM in TSOP packages. Each 184-pin DIMM uses gold contact fingers and requires
+2.5V. The electrical and mechanical specifications are as follows:
FEATURES:
Clock Cycle Time (tCK) 6ns (min.) / 12ns (max.)
Row Cycle Time (tRC) 60ns (min.)
Refresh Row Cycle Time (tRFC) 72ns (min.)
Row Active Time (tRAS) 42ns (min.) / 70,000ns (max.)
Single Power Supply of +2.5V (+/- .2V)
Power (IDD0) 1.800 W (operating)
UL Rating 94 V - 0
