A method for flexible bank addressing in digital computing-in-memory (DCIM). The method includes providing bank groups, each of the bank groups comprising a respective number of memory banks, each memory bank configured to store a corresponding portion of input feature map data. The method includes reading, during a first clock cycle, a first portion of the input feature map data from a first one of the bank groups and a second portion of the input feature map data from a second one of the bank groups. The method includes performing a first multiply-accumulate operation using the first portion and the second portion. The method includes reading, during a second clock cycle, a third portion of the input feature map data from the first bank group. The method includes performing a second multiply-accumulate operation using the second portion and the third portion.
