If you have a stock of NOS TMS4532 chips, store them correctly to prevent degradation.

The TMS4532 is most famous for its role in the . When Sinclair Research designed the 48K version of the Spectrum, they needed an additional 32K of RAM to supplement the "lower" 16K. tms4532

The TMS4532 represents a pivotal moment in semiconductor history. It bridged the gap between the first generation of 1Kb and 4Kb DRAMs and the later 64Kb and 256Kb chips that powered the IBM PC revolution. If you have a stock of NOS TMS4532

Note: Pin numbering may vary slightly. Always verify with the official Texas Instruments datasheet for your specific revision. The TMS4532 represents a pivotal moment in semiconductor

There is no direct drop-in modern replacement for a 4Kx8 DRAM because modern memory is organized differently (e.g., 64Mx8). However, for repairs, you can:

This in-depth guide explores everything you need to know about the TMS4532, from its technical specifications and pinouts to its notorious reputation as a "failed" part and why it remains a sought-after component for specific Commodore 64 restorations.
