    摘要： A non-volatile semiconductor memory device includes a memory cell array and a sense amplifier, the device being internally controlled to execute a write sequence with write pulse applications and write-verify operations repeated for writing a set of memory cells selected in the memory cell array, wherein the sense amplifier performs a write speed verify operation for detecting write speed of plural memory cells to be written into a certain data state after a certain write pulse application at the beginning of the write sequence, thereby getting discriminating data for classifying the plural memory cells into first and second cell groups, and after the write speed verify operation, the first and second cell groups are alternately written on different write conditions from each other with reference to the discriminating data.

    摘要： A non-volatile semiconductor device has a memory cell array having electrically erasable programmable non-volatile memory cells, reprogramming and retrieval circuits that temporarily store data to be programmed in the memory cell array and sense data retrieved from the memory cell array. Each reprogramming and retrieval circuit has a first latch and a second latch that are selectively connected to the memory cell array and transfer data each other. A controller controls the reprogramming and retrieval circuits on data-reprogramming operation to and data-retrieval operation from the memory cell array. Each reprogramming and retrieval circuit has a multilevel logical operation mode and a caching operation mode. In the multilevel logical operation mode, re-programming and retrieval of upper and lower bits of two-bit four-level data is performed using the first and the second latches in storing the two-bit four-level data in one of the memory cells in a predetermined threshold level range. In the caching operation mode, data transfer between one of the memory cells selected in accordance with a first address and the first latch is performed while data transfer is performed between the second latch and input/output terminals in accordance with a second address with respect to one-bit two-level data to be stored in one of the memory cells.

    摘要： A non-volatile semiconductor memory includes a memory cell array having a plurality of electrically-rewritable non-volatile memory cells. The memory cell array is provided with an initially-setting data area, programmed in which is initially-setting data for deciding memory operation requirements. The non-volatile semiconductor memory also includes an initial-set data latch. The initially-setting data of the memory cell array is read out and transferred to the data latch in an initially-setting operation.
