Latest Patents

Masaki Unno's latest patents include a high-performance semiconductor memory device that allocates different page addresses to multiple bits of memory cells. This semiconductor memory device features a memory cell array with numerous memory cells, each capable of storing multiple bits of data. The controller within the device executes write operations that allow user data to be written in at least one of the plural bits, while prescribed data fills the remaining bits. This design results in a reduced number of user data bits stored compared to the total bits each memory cell can accommodate.

Another notable patent involves a semiconductor memory device that comprises memory cell arrays, each containing blocks that serve as units of erase. These blocks include string-groups, with each string-group consisting of strings that incorporate a first transistor, memory cell transistors, and a second transistor connected in series. The first transistor links to a different bit line, while the second connects to the same source line. The memory cell arrays are equipped with distinct block and string address signals, allowing for precise identification and operation of each block and string-group.
