Abstract
A storage portion places data through a data output buffer on a data line D0.sub.P when a control line R00H becomes active, and places data through a data output buffer on a data line D0.sub.Q when a control line R03H becomes active. The storage portion further takes as input a signal on the data line D0.sub.P through a transmission gate when a control line W00H becomes active, and takes as input a signal on the data line D0.sub.Q through a transmission gate when a control line W003H becomes active. Thus, a storage device is provided to have the storage portion accessed by a plurality of access means at different addresses. It is thereby possible to select the optimal method of access to the storage portion, resulting in prevention of reduction of a program efficiency.
