WebRead Only Memory (ROM) As the name implies, a read-only memory (ROM) is a memory unit that performs the read operation only; it does not have a write capability. This … WebThe read cycle begins in T1 with the assertion of address latch enable (ALE) signal and also M / IO signal. During the negative going edge of this signal, the valid address is latched on the local bus. The BHE and A0 signals address low, high or both bytes. From T1 to T4 , the M/IO signal indicates a memory or I/O operation.
