Kingston Technology 128MB 266MHz DDR Non-ECC CL2.5 SODIMM KVR266X64SC25/128 Data Sheet

This document describes ValueRAM's 16M x 64-bit (128MB) CL2.5 SDRAM (Synchronous
DRAM) DDR266  memory module. The components on this module include four 16M x 16-bit
(4M x 16-bit x 4 Bank / 133MHz, 7.5ns, CL2.5)  DDR266 SDRAM in TSOP packages. This
1200-pin SODIMM uses gold contact fingers and requires +2.5V. The electrical and mechani-
cal specifications are as follows:

Clock Cycle Time (tCK)

7.5ns (min.) / 12ns (max.)

Row Cycle Time (t

RC

)

65ns (min.)

Refresh Row Cycle Time (tRFC)

75ns (min.)

Row Active Time (tRAS)

45ns (min.) / 120,000ns (max.)

Single Power Supply of

+2.5V (+/- .25V)

Power

1.650 W (operating power - one bank operation)

UL Rating

94 V - 0
