05515333 is referenced by 108 patents and cites 2 patents.

A semiconductor memory is provided which includes an electrically rewritable non-volatile semiconductor memory. A data control circuit is also provided which includes an ECC circuit and which operates to control the writing and reading operations of data to and from the non-volatile semiconductor memory. In order to temporarily hold data which is to written into the non-volatile semiconductor memory, a volatile cache semiconductor memory is utilized. This volatile cache semiconductor memory has a storage capacity which is equal to or less than the storage capacity of the non-volatile semiconductor memory itself. A data control circuit is also provided to read out data from the non-volatile semiconductor memory and the volatile cache semiconductor memory, and to transfer the data from the volatile semiconductor to the non-volatile semiconductor memory.
