Abstract
A system implementing parallel memory error detection and correction divides data having a word length of K bits into multiple N-bit portions. The system has a separate error processing subsystem for each of the N-bit portions, and utilizes each error processing subsystem to process the associated N-bit portion of the K-bit input data. During memory write operations, each error processing subsystem generates parity information for the N-bit data, and writes the N-bit data and parity information into a separate memory array that corresponds to the error processing subsystem. During memory read operations, each error processing subsystem reads N-bits of data and the associated parity information. If, based on the parity information, an error is detected from the N-bit data, the error processing subsystem attempts to correct the error. The corrected N-bit data from each of the error processing subsystems are combined to reproduce the K-bit word.
