Embodiment Construction

[0021] Implementation of a microcontroller in or associated with a non-volatile memory device according to an embodiment of the present invention will improve the development and manufacturing process of the memory device. In the embodiment of the present invention, when a change is required in the development and manufacturing process of the non-volatile memory device, the microcontroller can receive a new user command from the microcontroller through a user command interface such as the NVM operation process changes, including user commands such as program and erase. Then, during development and manufacturing, nonvolatile memory devices can operate according to these new commands with essentially little delay. In some embodiments of the invention, user commands can be changed and embedded into the non-volatile memory device while the memory device is already in production without substantially affecting the production process.

Abstract

A system and a method for operating a non-volatile memory (NVM) device including a micro-controller adapted to control peripheral circuitry associated with an NVM array. The method includes providing at least one operation command to the micro-controller of the NVM device and applying operating signals to peripheral circuitry of the NVM device to operate the NVM array based on at least one operation command. The system includes: (1) a NVM device with a NVM array adapted to store data and commands, peripheral circuitry adapted to operate the NVM array and a micro-controller adapted to control the peripheral circuitry; and (2) an external device to provide at least one command to the micro-controller of the NVM device.

Description

technical field [0001] The present invention relates generally to non-volatile memory devices, and more particularly to improved fabrication and development of such memory devices. Background technique [0002] The manufacturing and development process of a new generation of integrated circuits (integrated circuit: IC) can usually last 18 to 21 months. This process typically includes more than a hundred steps during which thousands of copies of the IC are formed on a single wafer. The process usually begins with design steps such as system, logic, circuit and polygons design. Typically, the design step will last 12 months and tape-out of the designed IC can be obtained. Afterwards, the product finalization is shipped to fabrication, which can often become the basis for IC manufacturing. The fabrication of ICs can last 6-9 months, including front-end and back-end stages. The front-end phase usually includes wafer fabrication steps and will last 3 months, while the back-en...
