Memory Module Specification
KVR533D2N4/512
512MB 64M x 64-Bit DDR2-533
DESCRIPTION:
This document describes ValueRAM's 64M x 64-bit (512MB) DDR2-533 CL4 SDRAM
(S ynchronous DRAM) memory module. The components on this module include eight
64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-533 SDRAM in FBGA packages. This 240-pin
DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical
specifications are as follows:
FEATURES:
Clock Cycle Time (tCK) CL=4 3.75ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 55ns (min.)
Refresh to Active/Refresh Command Time (tRFC) 105ns
Row Active Time (tRAS) 40ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power (IDD0) 1.440 W (operating)
UL Rating 94 V - 0
CL4 240-Pin DIMM
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).
