Abstract
A circuit for testing a memory is provided. An input end of the memory is coupled to a register, and the circuit for testing the memory transmits data to the memory through the register. The circuit for testing the memory performs the following operations sequentially: writing a first data into a target address of the memory, all bits of the target address being at the same level, and all bits of the first data being at the same level; writing a second data to the target address of the memory, all bits of the second data being at the same level, and the second data being different from the first data; reading from the target address an output data; and determining whether the output data is correct.
