ThinkPad 256 MB 100MHz Non-Parity SDRAM - Overview
General Information
Obtain the benefits of a memory upgrade for your ThinkPad 390X, ThinkPad 600E or ThinkPad 600X system with the new 256MB 100MHz Non-Parity (NP) SDRAM Small Outline DIMM (SoDIMM).

SDRAM enables this memory upgrade to perform faster than either traditional fast page mode (FPM) or Extended Data Out (EDO) memory modes of operation.

SDRAM SoDIMM features access times that are synchronous to the system bus clock.

This memory is manufactured to stringent quality standards confirmed by constant sampling during the manufacturing process.
