MEMORY BUS OUTPUT DRIVER OF MULTI-BANK MEMORY DEVICE AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method for enabling low-area, low-power and high-speed output of read-out data in a selected bank in a memory having a multi-bank configuration.

SOLUTION: The method includes: receiving a first sense output and a second sense output of a sense amplifier at a first tri-state device coupled to a first bus 128; receiving the first sense output and the second sense output of the sense amplifier at a second tri-state device coupled to a second bus 130; and selectively activating one of the first tri-state device and the second tri-state device to drive the first bus or the second bus in response to a bus selection input.
