Latest Patents

One of Kanda's latest patents is a nonvolatile semiconductor memory device designed for writing multivalued data. This innovative memory cell can store two bits, with a memory array sense amplifier providing two bits during a verify operation. The memory cell's functionality is enhanced by a page buffer that stores a write target value for the corresponding memory cell. Additionally, a mask buffer defines the processing to be applied to each memory cell. The write driver applies a write pulse when the corresponding bit in the mask buffer is '0'. A verify circuit then compares the bits from the memory array sense amplifier with those in the page buffer, updating the mask buffer when a match is found.
