Patent number: 12245429Abstract: A semiconductor memory device is implemented as strings of storage transistors, where the storage transistors in each string have drain terminals connected to a bit line and gate terminals connected to respective word lines. In some embodiments, the semiconductor memory device includes a reference bit line structure to provide a reference bit line signal for read operation. The reference bit line structure configures word line connections to provide a reference bit line to be used with a storage transistor being selected for read access. The reference bit line structure provides a reference bit line having the same electrical characteristics as an active bit line and is configured so that no storage transistors are selected when a word line is activated to access a selected storage transistor associated with the active bit line.Type: GrantFiled: January 14, 2022Date of Patent: March 4, 2025Assignee: SUNRISE MEMORY CORPORATIONInventor: Christopher J.

Publication number: 20240395301Abstract: Technology is disclosed for a current source for reading a memory cell having a threshold switching selector. The current source may be operated in a first mode when turning on the threshold switching selector and in a second mode when sensing a voltage across the memory cell. The first mode may allow the use of the full range of the power supply voltage, which provides sufficient voltage across the memory cell to turn on the threshold switching selector. In the second mode the magnitude of the read current is less dependent on the voltage across the memory cell. The second mode therefore provides for accurate sensing of the memory cell. The first mode may also be used when writing the memory cell, which provides sufficient voltage across the memory cell to write the memory cell.Type: ApplicationFiled: July 27, 2023Publication date: November 28, 2024Applicant: Western Digital Technologies, Inc.Inventors: Christopher J.
