Memory Module Specification
KVR533D2E4/256
256MB 32M x 72-Bit DDR2-533
CL4 ECC 240-Pin DIMM
DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB) CL4 DDR2-533 SDRAM
(Synchronous DRAM) ECC memory module. The components on this module include
nine 32M x 8-bit (8M 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
Row Cycle Time (tRC)
3.75ns (min.) / 8ns (max.)
55ns (min.)
Refresh to Active/Refresh Command Time (tRFC)
Row Active Time (tRAS)
Single Power Supply of
Power (IDD0)
75ns
40ns (min.) / 70,000ns (max.)
+1.8V (+/- .1V)
1.620 W (operating)
94 V - 0
UL Rating
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).
