摘要:
An apparatus and methods for predicting and/or for calibrating memory yields due to process defects and/or device variations, including determining a model of a memory cell, identifying a subset of parameters associated with the model, determining and executing a refined model using the parameters, determining a predicted probability the simulated memory cell will be operational based on the simulated operation of the refined model, determining yield prediction information from the predicted probability, and determining the minimum number of repair elements to include in a memory array design to insure a desired yield percentage based on the yield prediction information.
