Introduction

ValueRAM's KVR533D2N4/512 64M x 64-bit (512MB) DDR2-533 CL4 SDRAM 240-pin (Synchronous 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 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).
