Description:

The TMS4164-20NL is a vintage 64K × 1-bit NMOS dynamic RAM (DRAM) chip developed by Texas Instruments. It was widely used in early personal computers, video terminals, and arcade machines during the 1980s. This chip stores 65,536 bits of data and is organized as 65,536 words of 1 bit each, making it ideal for use in memory banks where multiple chips were combined to form wider data buses.
