Abstract
A memory array comprising a matrix of cells each of which includes a pair of bipolar transistor inverters. The collector loads of the inverters are commonly connected to a first constant voltage buss. The emitters of the transistors are commonly connected through a second resistor to a second constant voltage buss. Separate writing and reading circuits are provided for each cell in the array so that array cells can be written into and read from simultaneously.
