Abstract

See full text

In a nonvolatile memory array that stores randomized data, the program level—the number of states per cell stored in a population of memory cells—may be determined from the aggregated results of a single read step. A circuit for aggregating binary results of a read step includes parallel transistors with control gates connected to the data latches holding the binary results, so that current flow through the combined transistors depends on the binary results.
