摘要： This invention relates to a memory apparatus or the like adaptable to a multi-value recording flash memory and others. A flash memory 10 is designed for 16-value (4-bit) recording. For a write operation, the encoder (12) converts input data Din into an abbreviated Reed-Solomon code to provide write data WD. The converter (13) converts the write data WD into four-bit parallel data. The converted data are fed and written to the each memory cell constituting cell arrays (11) successively. For a read operation, the converter (14) converts read data RD from the cell arrays (11) into one-byte (8-bit) parallel data and supplies the converted data to the decoder (15) for error correction in units of bytes, whereby output data Dout is obtained. Since the Reed-Solomon code is used, sufficient performance with a limited number of errors to be corrected can be obtained.

摘要： Three dual-port RAMs of the number of bits=8 and the number of words=4 are provided in a path memory circuit. Path selection information is sequentially written into the three RAMs every clock in accordance with the control of a control circuit. On the other hand, the path selection information is read out every clock from the RAMs in accordance with the control of the control circuit and is inputted as read path selection information or the like to a tracing circuit. The tracing circuit executes the tracing operation as many as three times on the basis of the read path selection information and trace starting state information which is formed by the control circuit. On the basis of a tracing result, the decoding data and a trace starting state in the subsequent clock are obtained.
