Gregory's ServerAn interesting die from 1982, maybe IBM. This is a 128-bit static RAM, but not a normal RAM. This is a test chip to see how different transistor sizes perform in the RAM's read and write circuits. 1/8

Each RAM cell consists of two inverters in a loop, a standard design. Two pass transistors select the cell for reading or writing. This cell has 6 transistors so it is known as a 6T cell. 2/8
