Abstract
A sequential access memory structure includes an output bus and a plurality of sequential access memories, each of which is connected to the output bus. Each memory includes a memory array having a plurality of sequentially readable memory elements, a carry output for producing a carry signal when reading of the array has been substantially completed, and a carry input for causing reading of the array in response to a carry signal. The carry output of each memory is connected to a carry input of one other downstream memory respectively in a chain arrangement, and the carry signals cause the arrays to be read sequentially onto the output bus. Each memory further comprises a read-write storage connected between the array and the output bus, the storage including a plurality of sections. Data from the array is loaded into one section of the storage while data is being read from another section of the storage onto the output bus. The sections of memory elements in the array comprise half-pages. The storage comprises two sections, each of which has a half-page of memory elements, and the carry output produces the carry signal prior to reading data from a last half-page of the array out …
