Abstract
An in-memory computing apparatus and a computing method thereof are provided. A memory array includes a shifted weight storage area that stores shifted weight values, a shift information storage area that stores the number of shift units, and a shift unit amount storage area that stores a shift unit amount. A shift restoration circuit restores a weight shift amount of a shifted sum-of-products according to the number of shift units of the shifted weight values and a column shift unit amount, so as to generate multiple restored sum-of-products.
