DATA ACCESS CIRCUIT FOR A MEMORY ARRAY Abstract of the Disclosure The present invention relates to a data access circuit. The circuit is comprised of an identifier which identifies selected multibit binary words to be extracted from a memory array containing n multibit binary words and an extractor for extracting the selected multibit binary words from the memory array. The extractor includes a reader for reading out the n multibit binary words from the memroy array. A unit is responsive to the reader for distributing the bits of the multibit binary words to time slots in frames on a time-division highway, each frame being of n bits duration and including one bit from each of the n multibit binary words. The extractor further includes a plurality of output units, each of which repetitively counts the bits on the time-division highway and extracts every nth bit counted. An enabling unit is included for enabling each of the output units at selected points in time, aligned in time with various time slots in a first one of the frames on the time-division highway. Each of the various time slots contain a first bit from one of the selected multibit binary words, whereby each of the output units extract one selected multibit binary word from the time-division highway.
