Abstract
A nonvolatile memory ('NVM') bitcell includes a capacitor, a transistor, and a tunneling device. The capacitor, transistor, and tunneling device are each electrically coupled to different active regions and metal contacts. The three devices are coupled by a floating gate that traverses the three active regions. The tunneling device is used to program and erase the device, allowing for faster page erasure, and thus allows for rapid testing and verification of functionality. The transistor is used to read the logical state of the floating gate. The capacitor and floating gate are capacitively coupled together, removing the need for a separate selection device to perform read, write, and/or erase operations.
