MULTIPLE INTERFACE MEMORY WITH SEGMENTED I/O COLUMNS RECONFIGURABLE WITH RESPECT TO THE INTERFACES

摘要

A memory (102) includes segmented I/O columns to provide access to data storage elements (105) in memory segments via multiple data I/O interfaces. A column segment control (107) in each column I/O path enables access to the data storage elements in a first mode by a first processor interface (108A). In a second mode, the column segment controls are used to partition the array and provide mutually exclusive access to subsets of the array to different interfaces (108A, 108B).
