摘要： A non-volatile semiconductor memory device includes a memory cell array having a plurality of multi-level memory cells connected in series. The plurality of multi-level memory cells forms a plurality of threshold distributions each of which corresponds to a status of a lower bit and a status of an upper bit, wherein a lower bit and an upper bit constitute a lower page and an upper page respectively. The status of the lower bit dichotomizes the threshold distributions into two groups and the status of the upper bit further dichotomizes each of two groups. When programming a memory cell of the upper page, higher potentials are applied to a non-selected word line adjacent to the selected word line than those applied to the non-selected word line when programming the memory cell of the lower page.

摘要： The device has a data write mode to boost a first boost channel region that contains a non-write selected memory cell and non-selected memory cells located closer to the first selection gate transistor, and a second boost channel region that contains non-selected memory cells located closer to the second selection gate transistor than the selected memory cell, both electrically separated from each other. In this mode, a write non-selection voltage applied to a non-selected memory cell next to the second selection gate transistor is switched, at least in two stages, between a lower voltage V1 than a write non-selection voltage Vm applied to other non-selected memory cells in the NAND cell unit and a higher voltage V2 than the lower voltage (V1

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 first and second latches that are selectively connected to the memory cell array and transfer data. A controller controls the reprogramming and retrieval circuits on a data-reprogramming operation to and a 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 to store 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.
