Abstract
A peripheral interface circuit and a peripheral memory system are provided. The peripheral interface circuit includes an interface sequencer, an input/output controller, a register unit and a data buffer. The interface sequencer receives requests from the input/output controller and accesses the peripheral memory in response to the requests. The data buffer is randomly accessed by address. If target data of the data access request exists in the data buffer, the input/output controller returns data from the data buffer in response to the request; if target data of the data access request does not exist in the data buffer, the input/output controller sends an interface request to the interface sequencer to access the peripheral memory and keeps a copy of at least the target data in the data buffer.
