Abstract
A memory card with block erasure-type nonvolatile memory units is connected to a host apparatus by an I/O interface. The memory includes a plurality of block-erasure type nonvolatile memory units, a control circuit for inputting/outputting data to the host apparatus and managing nonvolatile memory units and address data to the memory, and a programmable logic device which converts address data to select respective erasure blocks of nonvolatile memories in accordance with a program. The control circuit programs the programmable logic device so that the address data for selecting defective erasure blocks is converted to address data for selecting other usable erasure blocks.
