Abstract: A compute-in-memory (CIM) array module and a method for performing dynamic saturation detection for a CIM array are provided. The CIM array module includes a CIM array, saturation detection units (SDUs) and a controller. The CIM array includes selectable row signal lines, column signal lines and cells. Each cell is located at an intersection of a selectable row signal line and a column signal line, and each cell has a programmable conductance. The SDUs are selectively coupled to at least one column signal line, and each SDU is configured to, for each column signal line, generate an analog signal, and identify the column signal line as a saturated column signal line when a voltage of the analog signal is greater than a saturation threshold voltage, or a current of the analog signal is greater than a saturation threshold current.
