Patent number: 8374029Abstract: An electrically addressed non-volatile memory is maintained by measuring a voltage threshold for each selected memory cell in the electrically addressed non-volatile memory. The voltage threshold is a voltage around which a controllable voltage signal applied to a control gate of a selected memory cell produces a change in value read from the selected memory cell. A measured voltage threshold distribution of the measured voltage thresholds is generated for the selected memory cells. The voltage threshold distribution is analyzed to identify memory cells having greater probabilities of read errors, for example. In response to the analysis, an operating parameter that affects the memory cells identified as having greater probabilities of read errors is selectively changed.Type: GrantFiled: March 15, 2011Date of Patent: February 12, 2013Assignee: Texas Instruments IncorporatedInventors: Peggy Jean Liska, Aaron Jabari Russell, Anthony Scott Vaughan

Patent number: 8331126Abstract: Read and write operations of a non-volatile memory (NVM) bitcell have different optimum parameters resulting in a conflict during design of the NVM bitcell. A single bitline in the NVM bitcell prevents optimum read performance. Read performance may be improved by splitting the read path and the write path in a NVM bitcell between two bitlines. A read bitline of the NVM bitcell has a low capacitance for improved read operation speed and decreased power consumption. A write bitline of the NVM bitcell has a low resistance to handle large currents present during write operations. A memory element of the NVM bitcell may be a fuse, anti-fuse, eFUSE, or magnetic tunnel junction. Read performance may be further enhanced with differential sensing read operations.Type: GrantFiled: August 4, 2010Date of Patent: December 11, 2012Assignee: QUALCOMM IncorporatedInventor: Esin Terzioglu
