Description

The four photographs in the pdf file show the three hybrid arrays that comprise the SAM memory stack designed for Burroughs Corporation. Sixteen 64-bit P-channel MOS chips and a bipolar driver were mounted on a ceramic substrate to form 1024-bit memory planes. Multiple planes together with X and Y driver planes were assembled on top of each other to form a compact semiconductor memory system. Donated by Ed Turney. 4 scanned pages.
