Memory Module Specification KVR100X64SC2L/256 256MB Low Profile PC100 144-Pin CL2 SODIMM Memory Module DESCRIPTION: This document describes ValueRAM's CL2 32M x 64-bit (256MB) SDRAM (Synchronous DRAM) PC100 Small Outline DIMM memory module. The components on this module include sixteen 16M x 8-bit (4M x 8-bit x 4 Bank / PC100 components) 4K Refresh SDRAM in UBGA packages. This 144-pin SODIMM uses gold contact fingers and requires +3.3V. The electrical and mechanical specifications are as follows: FEATURES: CLK Cycle Time (tCC) Row Cycle Time (tRC) CLK to Output (tSAC) Single Power Supply of Power UL Rating min. = 10ns (CAS Latency = 2) / max. = 1000ns 70ns max. = 6ns (CAS Latency = 2) +3.3V (+/- .3V) 3.696 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 1.200" (30.48mm). 2.66 (67.56) Units : Inches (Millimeters) 2.50 (63.60) 59 61 0.91 (23.20) 0.13 (3.30) 143 1.29 (32.80) 0.18 (4.60) 0.083 (2.10) 0.10 (2.50) 1.00 0.79 (20.00) 0.24 (6.0) 1 (25.40) 2-R 0.078 Min (2.00 Min) 0.16 ± 0.039 (4.00 ± 0.10) 2-f 0.07 (1.80) Tolerances : ±.006(.15) unless otherwise specified Z Y 0.15 (3.70) 60 62 144 0.10 Min (4.00 Min) 0.157 Min 0.125 Min (3.20 Min) 0.150 Max (3.80 Max) 0.04 ± 0.0039 (1.00 ± 0.10) 0.16 ± 0.0039 (4.00 ± 0.10) 0.06 ± 0.0039 (1.50 ± 0.1) Detail Z (2.55 Min) 2 0.024 ± 0.001 (0.60 ± 0.05) 0.01 Max (0.25 Max) 0.03 TYP (0.80 TYP) Detail Y Figure 1: KVR100X64SC2L/256 144-Pin SDRAM Module Document No. VALUERAM0205-001.B00 04/28/02
