Abstract: Disclosed is an ultra-large scale in-memory computing core circuit for solving IR-Drop issues. The disclosure determines that the accuracy degradation caused by line resistance is an approximate linear error by analyzing the inherent physical equations of the line resistance network. Through analysis of the approximate analytical equation, it is found that the linear error is only related to the parameters of the line resistance network. This means that different input voltage vectors produce the same approximate linear error of the column output current.
