Abstract
The present invention relates to memory and methods for storing/retrieving data in/from the memory that is accessed by at least two distinct data uses of different actual word widths. A memory for storing addressable binary data comprises a data storage organized in rows and columns of bit array cells, row address decoder and driver for addressing a selected row of bit array cells, column drivers for driving selected columns of bit array cells, and a bus switch port for selectively transferring data between the data storage and a first data bus with a first bus word width p and a second data bus with a second bus word width q smaller than the first bus word width p.
