Abstract
A memory storage device includes: a memory array for generating a cell current dependent to an input and transconductance of memory cells of the memory array; a reference array for generating a reference current; an ADC for performing analog-digital-conversion on the cell current based on the reference current to generate a digital output; and a memory controller for generating an output based on the input and the digital output of the ADC. The output of the memory controller indicates an inner product of the input and a weight, the weight including a positive weight and a negative weight. The positive weight is implemented by the transconductance of the memory cells of the memory array. The negative weight is implemented by transconductance of reference cells of the reference array or implemented by a shifting number of a shifter in the memory controller.
