MEMORY SYSTEM AND INFORMATION PROCESSING SYSTEM

摘要

A memory system that includes an error check and correct (ECC) circuit is provided. The memory system includes a memory, a circuit, and a processor. The memory system has a function of receiving write data from the outside. The memory includes a user data region, a first management region, and a second management region. The user data region stores the write data. The circuit has a function of performing ECC processings on the write data read from the user data region. The first management region stores data that indicates whether the user data region has stored the write data or not. The second management region stores data that indicates whether the circuit has performed the ECC processings on the write data read from the user data region or not.

1. A memory system comprising:
a memory including a user data region, a first management region, and a second management region; a circuit; and a processor, wherein the memory system is configured to receive write data from an outside, wherein the user data region includes a user data block storing the write data, wherein the circuit is configured to sequentially perform error check and correct processings on the write data read from the user data block, wherein the first management region stores first data, the first data has a first value showing that the user data block does not store the write data or a second value showing that the user data block stores the write data, and wherein the second management region stores second data, the second data has a third value showing that the circuit does not perform the error check and correct processings on the write data read from the user data block or a fourth value showing that the circuit has performed the error check and correct processings on the write data read from the user data block.
