PURPOSE:To provide a storage reproducing system capable of detecting an address error by a comparatively compact circuit without being influenced by the size of address information. CONSTITUTION:This memory reproducing system is provided with a memory 1, a data register 2, an ECC register 3, an address register 4, an 11 ECC generating circuit 5, an ECC check correcting circuit 6, a parity generating circuit 7 for generating a parity from the address value of the register 4, an EOR circuit 8 for executing the inversion/noninversion of write data, an EOR circuit 10 for inverting an address parity outputted from circuit 7 in accordance with the checked result of the circuit 6, and an EOR circuit 9 for executing the inversion/non-inversion of read data in accordance with the address parity and constituted so as to verify an address error by inverting/non-inverting writing data in accordance with the address parity, and at the time of reading out the inverted/non-inverted data from the memory 1, inverting/non-inverting the data in accordance with the address parity and an ECC check result, thin, verifying the address error. |
