A method of operating a semiconductor inference device that includes the steps of writing one of multiple analog weight values to memory cells of a non-volatile memory (NVM) array, receiving inputs through a bus system, performing multiply accumulate (MAC) operations based on the inputs and the stored analog weight values, converting results of the MAC operations to outputs, and transmitting the outputs through the bus system.

Silicon-oxide-nitride-oxide-silicon based multi-level non-volatile memory device and methods of operation thereof

A semiconductor inference device that has a non-volatile memory (NVM) array including NVM cells arranged in rows and columns, in which each NVM cell comprises a charge trapping transistor configured to store one of N&#xd7;analog values corresponding to N&#xd7;levels of its drain current (ID) or threshold voltage (VT) levels, representing N&#xd7;weight values for multiply accumulate (MAC) operations. The semiconductor inference device also includes digital-to-analog (DAC) function and multiplexor (mux) function configured to generate an analog MAC result based on the digital inputs converted results and the weight values read results, and analog-to-digital (ADC) function configured to convert the analog MAC result of the mux function to a digital value. Other embodiments of the semiconductor inference device and related methods and systems are also disclosed.

A memory including an array of non-volatile latch (NVL) cells and method of operating the same are provided. In one embodiment, each NVL cell includes a non-volatile portion and a volatile portion. The non-volatile portion includes a first non-volatile memory (NVM) device and a first pass gate transistor coupled in series between a first output node and a bitline true, and a second NVM device and a second pass gate transistor coupled in series between a second output node and a bitline complement. The volatile portion includes cross-coupled first and second field effect transistors (FET), the first FET coupled between a supply voltage (VPWR) and the first output node, and the second FET coupled between VPWR and the second output node. A gate of the first FET is coupled to the second output node, and a gate of the second FET is coupled to the first output node.
