Multiport memory cell having a reduced number of write wordlines

摘要

A multiport memory cell having a reduced number of write wordlines is disclosed. The multiport memory cell capable of simultaneously reading data from and writing data to a storage cell comprises a storage cell for storing data, a decoder, write wordlines, write bitlines, read wordlines, and read bitlines. The write wordlines and the write bitlines are utilized to input write data into the storage cell. The read wordlines and the read bitlines are utilized to output data from the storage cell. The write bitlines are directly coupled to the storage cell, and some or all of the write wordlines are coupled to the storage cell via the decoder for the purpose of wire reduction. Similar to the write bitlines, all the read bitlines and read wordlines are directly coupled to the storage cell.
