Method and Apparatus for Systematic and Random Variation and Mismatch Compensation for Multilevel Flash Memory Operation |
摘要 |
Method and means for random or systematic mismatch compensation for a memory sensing system are disclosed. A sense amplifier includes a bulk voltage source to set the bulk of the sensing transistor to be a voltage different than the voltage driving the sensing transistor. For an NMOS sensing transistor, a triple well is used with the variable bulk voltage. Differential sense amplifiers with various offset compensation are included. Intentional offset creation for useful purpose is also included.
