AIM device and method of testing the AIM device

摘要

Disclosed is an AIM device in which a multiply-accumulate (MAC) operator is integrated in a memory media. The MAC operator includes a first multiplication operator that performs a first multiplication operation on first first data and first second data input to each of the two first input terminals, and a first multiplication operator that is input to each of the two second input terminals. A multiplication operation unit including a second multiplication operator that performs a second multiplication operation on the second first data and the second second data, and first multiplication result data output from the first multiplication operator and the second multiplication operator. And an addition operation unit that performs an addition operation on the second multiplication result data. In response to the test mode signal of the first level, the MAC operator equally inputs the first first data and the first second data to each of the first input terminals and each of the second input terminals, and then performs a first multiplication operation and a second operation. It is configured to perform a multiplication operation and an addition operation to perform a test operation on the multiplication operation unit.
