Abstract
A semiconductor storage circuit includes a memory core which includes multiple memory cells; an error checking and correction (ECC) encoder; and an ECC decoder. The memory core is activated in response to input of a command for each operation cycle. The ECC encoder performs ECC encoding of input data which is input together with a write command and thus generates ECC data, and generates write data including the input data and the ECC data. The ECC decoder performs ECC decoding of read data which has been read from the memory core according to a read command, using ECC data included in the read data, and thus generates output data. An adjustment is made to equalize a delay from input of a write command until activation of the memory core and a delay from input of a read command until activation of the memory core.
