Memory Module Specification KVR667D2N5/512 512MB 64M x 64-Bit DDR2-667 CL5 240-Pin DIMM

DESCRIPTION: This document describes ValueRAM's 64M x 64-bit (512MB) DDR2-667 CL5 SDRAM (Synchronous DRAM) memory module. The components on this module include eight 64M x 8-bit (16M 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 Row Cycle Time (tRC) Refresh to Active/Refresh Command Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating

3ns (min.) / 8ns (max.) 54ns (min.) 105ns 39ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 1.296 W (operating) 94 V - 0

Note: The module defined in this data sheet is one of several configurations available under this part number. While all configurations are compatible, the DRAM combination and/or the module height may vary from what is described here. However, in no configuration will the module height exceed 1.250" (31.75mm). 133.35
