Title: Device and method for reading data in memory
IPC: G06F7/46
Filed: 2021-04-16
Abstract: In a computer-in-memory (CIM) system, from a CIM memory circuit, a current signal indicating a result of a multiply-accumulate operation is calculated through a comparison to a reference current generated by a current digital-to-analog converter ("DAC") circuit. The memory circuit can include a non-volatile memory ("NVM") element, and the element can be a multi-level or two-level NVM element. A characteristic size of the memory element can be binarily weighted to be matched with each place value of a multi-bit weighted value and/or a multi-bit input signal. Alternatively, an NVM element of the same size can be used to drive a transistor of a binarily weighted size. A current comparison operation can be performed faster than voltage calculation. In some embodiments, a simple clock-gate switch can be used such that a current summing branch can generate a uniform current. The clock-gate switch also can reduce static current consumption as a cell current functions to limit on-in time.
