摘要： A memory cell array 1 has the arrangement of a plurality of cores, each of which comprises one block or a set of a plurality of blocks, each block defining a range of memory cells serving as a unit of data erase. A core selecting part for selecting an optional number of cores to write/erase data is provided for writing data in memory cells in cores selected on the basis of a write command and for erasing data from selected blocks in cores selected on the basis of an erase command. Thus, there is realized a free core system capable of reading data out from memory cells in unselected cores while writing/erasing data in cores selected by the core selecting part.

摘要： A nonvolatile semiconductor memory includes a memory cell array and a redundant cell array, and while a data write operation or a data erase operation is carried out in one of banks in the memory cell array, a data read operation can be carried out in the other banks. The redundant cell array has one or more spare blocks and is provided independently of the banks to relieve a defective memory cell of the memory cell array by substituting the spare block for a defective memory block in any of the blocks. The memory block is active when an access block address to be accessed in the memory cell array in the data write or erase operation or the data read operation does not coincide with the defective block address in the defective address storing circuit, whereas the spare block is active when the access block address coincides with the defective block address in the defective address storing circuit.
