Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 32M x 64-bit (256MB) DDR2-667 CL5 SDRAM
(Synchronous DRAM) memory module. The components on this module include eight
32M x 8-bit (8M x 8-bit x 4 Bank) DDR2-667 SDRAM in FBGA packages. This 240-pin
DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical
specifications are as follows:
FEATURES:
Clock Cycle Time (tCK) CL=5 3ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 54ns (min.)
Refresh to Active/Refresh Command Time (tRFC) 75ns
Row Active Time (tRAS) 39ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power 1.440 W (operating)
UL Rating 94 V - 0
