Abstract
A hierarchical memory system in which a lower level transfers data serially to an upper level and in parallel to a yet lower level. The lower level includes a two-port memory chip having a wide buffer for parallel accesses to the memory array, to the yet lower level, and to a serial buffer. The serial buffer is serially accessed to the upper level simultaneously with accesses to the wide buffer.
