Latest Patents

Yoshimura is associated with 1 patent, titled “Semiconductor Memory Device.” The invention describes a control circuit that performs data writing in three stages: erasing the memory cell, preliminarily programming it to a temporary threshold distribution corresponding to the write data, and then programming it to the final distribution. During reading, the circuit adjusts the read-pass voltage applied to a neighboring word line according to the neighboring memory cell’s threshold value, then determines whether the first memory cell is at the erase level.
