Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 32M x 64-bit (256MB) CL2.5 SDRAM (Synchronous
DRAM) DDR266 memory module. The components on this module include eight 16M x 16-bit
(4M x 16-bit x 4 Bank / 133MHz, 7.5ns, CL2.5) DDR266 SDRAM in TSOP packages. This
200-pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical
specifications are as follows:
FEATURES:
Clock Cycle Time (tCK) 7.5ns (min.) / 12ns (max.)
Row Cycle Time (tRC) 65ns (min.)
Refresh Row Cycle Time (tRFC) 75ns (min.)
Row Active Time (tRAS) 45ns (min.) / 120,000ns (max.)
Single Power Supply of +2.5V (+/- .25V)
Operating (IDD0) 2.350 W
UL Rating 94 V - 0
