Memory Module Specification KVR400D2N3K2/1G 1GB (512MB 64M x 64-Bit x 2 pcs.) DDR2-400 CL3 240-Pin DIMM Kit DESCRIPTION: ValueRAM's KVR400D2N3K2/1G is a kit of two 64M x 64-bit (512MB) DDR2-400 CL3 SDRAM (Synchronous DRAM) memory modules. Total kit capcity is 1GB (1024MB). The components on each module include eight 64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-400 SDRAM in FBGA packages. Each 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=3 Row Cycle Time (tRC) Refresh to Active/Refresh Command Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating 5ns (min.) / 8ns (max.) 55ns (min.) 105ns 40ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 1.368 W (operating per module) 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 Units : Millimeters (2X)4.00 131.35 10.00 128.95 30.00 (2) 2.50 A 17.80 2.30 SPD B 63.00 2.7 55.00 1.270 ± 0.10 4.00 4.00 3.00 2.50±0.20 5.00 0.80±0.05 3.80 2.50 1.50±0.10 Detail A 0.20 1.00 4.00 Detail B Figure 1: KVR400D2N3K2/1G 240-Pin DIMM Document No. VALUERAM0365-001.A00 10/11/04
