Abstract: A method and apparatus for storing in a read only memory a matrix having one or more rows each with a majority of '''' 1'''' bits. There is formed the complement of each of those rows having a majority of '''' 1'''' bits to form a new matrix wherein no row has a majority of '''' 1'''' bits. The new matrix is stored in a read only memory. Upon reading out one or more rows of the matrix the bits of the complemented rows are reinverted.

Abstract: An electronic data storage which operates as a DC stable storage array, but retains the advantages of an AC stable storage cell circuit. The AC stable storage cells are regenerated at a frequency asynchronous with respect to the storage cycle time. Gating means inhibit the regenerating signals when the system desires access, thereby permitting the storage cells to be accessed for information at any time in a completely random access mode.
