摘要： A read-only memory plane has a plurality of storage elements arranged in a matrix of columns and rows. Drive means are associated with the columns of elements for energizing the elements and a plurality of sense lines are associated with the row of elements for determining the information content of the storage elements. A second matrix of storage elements is within the memory plane in tandem with the first matrix of elements. A second set of drive means and sense lines are provided for the read-out of the second array of storage elements. The information read-out is manifest in the presence or absence of signals induced in the sense lines when the storage elements are energized. Pairs of sense lines one in each pair from the first array and the other from the second array, are coupled to respective differential amplifiers for amplifying the induced signals and for rejecting any stray signals including background noise which would be common to the two arrays.
