KVR266X64SC25

Memory Module Specification KVR266X64SC25/512 DESCRIPTION: This document describes ValueRAM's 64M x 64-bit (512MB) CL2.5 SDRAM (Synchronous DRAM) DDR266 memory module. The components on this module include sixteen 32M x 8-bit (8M x 8-bit x 4 Bank / 133MHz, 7.5ns, CL2.5) DDR266 SDRAM in uBGA packages. This 200-pin 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 7.5ns (min.) / 12ns (max.) 65ns (min.) 75ns (min.) 45ns (min.) / 120,000ns (max.) +2.5V (+/- .25V) 2.900 W 94 V - 0 512MB 64M x 64-Bit DDR266 CL2.5 200-Pin SODIMM 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) 0.16 ± 0.039 (4.00 ± 0.10) Full R 2x 0.24 (6.0) 1 39 41 199 0.086 2.15 0.456 11.40 0.07 (1.8) 0.098 2.45 2 40 42 0.17 (4.20) 0.096 (2.40) Z 1.896 (47.40) Units : Inches (Millimeters) Y 200 Tolerances : ±.006(.15) unless otherwise specified Figure 1: KVR266X64SC25/512 200-Pin DDR266 Document No. VALUERAM0249-001.A00 06/12/02 0.79 (20.00) 2-f 0.07 (1.80) 1.25 (31.75)
