DESCRIPTION:
This document describes ValueRAM's 256M x 72-bit (2048MB), CAS Latency 2.5 SDRAM
(Synchronous DRAM) Registered DDR266 ECC memory module. The components on this
module include eighteen stacked 256M x 4-bit, 133MHz, 7.5ns, CL2.5 SDRAM 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:
Document No. VALUERAM0239-001.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 1.700" (43.18mm).
