Memory Module Specification KVR333X64SC25/512 512MB 64M x 64-Bit DDR333 CL2.5 200-Pin SODIMM DESCRIPTION: This document describes ValueRAM's 64M x 64-bit (512MB) DDR333 CL2.5 SDRAM (Synchronous DRAM) memory module. The components on this module include sixteen 32M x 8-bit (8M x 8-bit x 4 Bank) DDR333 SDRAM sealed in uBGA packages. This 200pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical specifications are as follows: FEATURES: Clock Cycle Time (tCK) Row Cycle Time (tRC) Refresh Row Cycle Time (tRFC) Row Active Time (tRAS) Single Power Supply of Operating (IDD0) UL Rating 6ns (min.) / 12ns (max.) 60ns (min.) 72ns (min.) 42ns (min.) / 70,000ns (max.) +2.5V (+/- .25V) 3.525 W 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). 2.66 (67.60) 2.50 (63.60) 39 41 0.456 11.40 0.086 2.15 1.896 (47.40) 2-f 0.07 (1.80) Units : Inches (Millimeters) Z 0.098 2.45 2 199 0.17 (4.20) 0.096 (2.40) 0.07 (1.8) 0.79 (20.00) 0.24 (6.0) 1 1.25 (31.75) Full R 2x 0.16 ± 0.039 (4.00 ± 0.10) 40 42 Protective Cover Y 200 Protective Cover Tolerances : ±.006(.15) unless otherwise specified Figure 1: KVR333X64SC25/512 200-Pin SODIMM Document No. VALUERAM0300-001.A00 06/13/03
