Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 8M x 64-bit (64MB), CAS Latency 3 (CL3) SDRAM
(Synchronous DRAM) 100MHz memory module. The components on this module include
eight 8M x 8-bit (2M x 8-bit x 4 Bank / PC100 components) SDRAM in TSOP packages.
This 168-pin DIMM 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 = 3) / max. = 1000ns
Row Cycle Time (tRC) 70ns
CLK to Output (tSAC) max. = 6ns (CAS Latency = 3)
Single Power Supply of +3.3V (+/- .3V)
Power 2.772 W (operating)
UL Rating 94 V - 0
Document No. VALUERAM0043-001.B00

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 1.375" (34.92mm).
