Abstract
A digital computer memory made up of a plurality of read only memory components arranged in a matrix of rows and columns. The outputs of the columns of memory components are connected to a voltage source and load resistors to provide the output terminals of the memory. Sets of digital words having at least a field or portion of a field with bits represented by the same logical state are grouped in such memory so that, when a word in such set is addressed, the bits in such field are produced at the output terminals by the volage source and load resistors. With such arrangement the number of read only memory components required in such memory is reduced.
