Latest Patents

Kawada's latest patents include a semiconductor integrated circuit device designed to reduce the number of memory gate drivers. This invention aims to lessen the frequency of disturbance occurrences in a memory array configuration that implements writing in small byte units. The memory array consists of multiple sub-arrays, MG transfers, SL drivers, and CG drivers. Each sub-array contains several memory gate lines, control gate lines, source lines, and bit lines, with memory cells arranged at the intersections of these lines. By optimizing the arrangement of control gate lines, CG drivers, source lines, and SL drivers, Kawada's design minimizes the units in which data is written, thereby reducing adverse effects without increasing the circuit size.

Another notable patent is for a semiconductor device that includes a nonvolatile memory featuring a memory array with 1-bit twin cells. Each twin cell comprises electrically rewritable first and second storage devices that hold binary data based on their threshold voltage differences. This design allows for improved retention performance, as the two memory cells can maintain different data even if one cell's retention deteriorates. The device includes a read circuit for differentially amplifying the complementary data output from the twin cells, ensuring accurate information retrieval.
