Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB), CAS Latency 2.5 SDRAM
(Synchronous DRAM) low-profile Registered DDR266 ECC memory module. The compo-
nents on this module include nine 32M x 8-bit (8M x 8-bit x 4 Bank / 133MHz, 7.5ns, CL2.5
components) SDRAM in TSOP packages and three 16-bit drivers in TSSOP packages. This
184-pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical
specifications are as follows:
FEATURES:
Clock Cycle Time (tCK) 7.5ns (min.) / 12ns (max.)
Row Cycle Time (tRC) 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 (IDD0) 4.725 W (operating)
UL Rating 94 V - 0
Part No. VALUERAM0255-001.A00

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 1.2" (30.48mm).
