Wrapper circuit and method for interfacing between non-muxed type memory controller and muxed type memory

摘要

A wrapper circuit effectively converts a muxed-type memory (having time-multiplexed address and data lines) into a non-muxed type memory as seen by the controller (a non-muxed type memory controller). Wrapper circuit includes a select circuit (e.g., multiplexer) and an input/output buffer. The select circuit receives write data and an address from a non-muxed type memory controller and selects either the write data or the address according to a first control signal. The input/output buffer receives the selection among the write data and the address and passes the write data or the address to a muxed type memory. The input/output buffer also passes read data received from the memory to the memory controller.
