Abstract
Disclosed is testing multi-port array macros where latches and logic are used to control the relationship between the write and read port of the array. This makes allowance for many different configurations of reading and writing the array. This also allows for greater test coverage than the previous method, which simply inverted one of the write address bits to form the read address.
