Abstract:
A random bit cell includes a latch and a nonvolatile memory cell. The nonvolatile memory cell includes a storage circuit, a control element, an erase element, and a read circuit. The storage circuit is coupled to a first terminal of the latch. The storage circuit includes a floating gate transistor having a first terminal, a second terminal, and a floating gate. The control element has a first terminal coupled to a control line, and a control terminal coupled to the floating gate of the floating gate transistor. The erase element has a first terminal coupled to an erase line, and a control terminal coupled to the floating gate of the floating gate transistor. The read circuit is coupled to a bit line, a select gate line, and the floating gate of the floating gate transistor.
