KVR400D2N3K2

Memory Module Specification KVR400D2N3K2/512 DESCRIPTION: ValueRAM's KVR400D2N3K2/512 is a kit of two 32M x 64-bit (256MB) DDR2-400 CL3 SDRAM ( S ynchronous D RAM ) memory modules. Total kit capacity is 512MB. The components on each module include four 32M x 16-bit (8M x 16-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.) 75ns 40ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 0.828 W (operating per module) 94 V - 0 512MB (256MB 32M x 64-Bit x 2 pcs.) DDR2-400 CL3 240-Pin DIMM Kit 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). 133.35 131.35 128.95 Units : Millimeters (2X)4.00 SPD 10.00 30.00 2.30 (2) 2.50 A 63.00 B 55.00 17.80 2.7 1.270 ± 0.10 3.00 5.00 4.00 4.00 2.50±0.20 0.80±0.05 3.80 2.50 0.20 4.00 1.50±0.10 1.00 Detail A Detail B Figure 1: KVR400D2N3K2/512 240-Pin DIMM Document No. VALUERAM0363-001.A00 10/11/04
