ABSTRACT:
A semiconductor memory circuit provided with an improved serial access circuit arrangement is disclosed. The memory circuit includes first and second memory arrays, a common data hold circuit, a first control circuit for enabling one of the first and second memory arrays, and a data transfer circuit which transfers data derived from the first memory array to the common data hold circuit when the first memory array is enabled and transfers data derived from the second memory array to the common data hold circuit when the second memory array is enabled.
