Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's CL2 16M x 64-bit (128MB) SDRAM (Synchronous
DRAM) PC100 Small Outline DIMM memory module. The components on this module include
eight 8M x 16-bit (2M x 16-bit x 4 Bank / PC100 components) 4K Refresh SDRAM in TSOP
packages. This 144-pin SODIMM uses gold contact fingers and requires +3.3V. The electrical
and mechanical specifications are as follows:
FEATURES:
CLK Cycle Time (tCC) min. = 10ns (CAS Latency = 2 / max. = 1000ns)
Row Cycle Time (tRC) 70ns
CLK to Output (tSAC) max. = 6ns (CAS Latency = 2)
Single Power Supply of +3.3V (+/- .3V)
Power 2.244 W (operating)
UL Rating 94 V - 0
Document No. VALUERAM0228-001.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 1.250" (31.75mm).
