ABSTRACT:
A read-only memory suitable for use as the control ROM of a microprocessor has each output line divided into first and second parts. Memory elements connected to the first parts are responsive to early-occurring input signals and memory elements connected to the second parts are responsive to late-occurring input signals. Switch means are provided to enable the output signals from the second parts of the output lines to be generated in response to a late-occurring input signal independently of the loading of the memory elements connected to the first parts of the output lines.
