Abstract

PURPOSE: To use effectively memory regions by realizing error correction by one- bit and two-bit error detection codes (SEC.DEC) by composing the memory element, corresponding to an associative level, of a fixed number of one-bit memory regions.
CONSTITUTION: Memory elements 7-1... 7-M of one bit by (n) words by (m) associative levels of buffer memory tag part 6 of M bits by N words by I associative levels are composed of one-bit memory regions 8-1...8-M, and ..., 11-1... 11-M, and main memory unit 5 consists of A columns by B sets. In accordance with address information, decoder 12 attains access to tag 6 corresponding to a column number to read set number information in regions 8-1...W11-1... at the same time, and data are transferred from, stored in and updated in comparators 14-1.... This constitution provides error detection using SEC.DEC even an error due to one of element 7-1... would be of one bit and the number of N words of tag part 6 can be equalized to that of columns of unit 5, so that memory regions can effectively be used.
