    摘要: According to a method of controlling the operation of a flash memory device including a number of memory blocks, a memory block of the memory blocks is first selected as a reference block. A program operation is performed on a memory cell included in the reference block. In order to check an operating characteristic of the reference block, a threshold voltage level of the programmed memory cell is read. Parameters for performing an operation of the flash memory device are determined based on the operating characteristic of the reference block. The parameters are stored in the reference block.

    摘要: The present invention relates to a flash memory device. The present invention relates to a flash memory device in which a capacitor of a given capacitance is connected between a bit line connected to a drain region and a ground line within a flash cell array, and method of erasing the same. Therefore, the present invention can reduce the time and power consumption in the cell erase operation, by accelerating an increase of hot carriers generated in a diode reverse-bias state between the drain region and a semiconductor substrate upon an erase operation of the cell to prevent over-erase or non-erase of the cell by means of hot carriers and by thus solving an over-erase problem of the cell without requiring additional pre-programming and verification operation and additional post-programming and verification operation.
