Abstract
A method of and apparatus for handling errors occurring in data stored in memory is presented. Data to be stored in a buffer memory is applied to a generator matrix to generate parity check bits. The parity check bits are stored in the buffer memory along with the data. The stored data and parity check bits are read and the read data is used to regenerate the parity check bits. A result produced from the stored and regenerated parity check bits is usable to directly identify a location of an erroneous bit of the data in the buffer memory.
