ECC control apparatus

Abstract

An ECC control apparatus is to be connected between a host and a memory. The apparatus comprises a first input/output circuit, a detecting circuit, a code-generating circuit, a code-inserting circuit, a second input/output circuit. The first input/output circuit inputs and outputs data to and from the host. The detecting circuit detects a protected-data region and a redundant region of write data input to the first input/output circuit and having a predetermined data length. The code-generating circuit generates an error-correction code for correcting errors in data stored in the protected-data region. The code-inserting circuit inserts the error-correction code in the redundant region. The second input/output circuit inputs and outputs data to and from the memory.
