MEMORY DEVICE AND METHOD OPERABLE TO PROVIDE MULTI-PORT FUNCTIONALITY THEREOF

摘要

A memory device operable to provide multi-port functionality, which may comprise a single-port memory having a first operating frequency that is at least twice of a second operation frequency of a multi-port memory, a read synchronization module that synchronizes a set of read signals from the second operation frequency to the first operating frequency, a write synchronization module that synchronizes a set of write signals from the second operation frequency to the first operating frequency, a read/write signal selector that integrates a set of synchronized read signals and a set of synchronized write signals into a set of input control signals of the single-port memory, and a read out data synchronization module configured to synchronize a set of read out data from the single-port memory with the second operation frequency of the multi-port memory.

1. A memory device operable to provide multi-port functionality, comprising:
a single-port memory having a first operating frequency that is at least twice of a second operation frequency of a multi-port memory; at least one read synchronization module synchronizing a set of read signals from the second operation frequency to the first operating frequency; at least one write synchronization module synchronizing a set of write signals from the second operation frequency to the first operating frequency; a read/write signal selector integrating a set of synchronized read signals and a set of synchronized write signals into a set of input control signals of the single-port memory; and a read out data synchronization module configured to synchronize a set of read out data of the single-port memory from the first operating frequency to the second operation frequency of the multi-port memory.
