Tri-state output driver arranging method and memory device using the same
First Claim
1. A device comprising:
- a first sensing amplifier to amplify data received from a memory array;
a first driver to generate a first tri-state signal responsive to the amplified data from the first sensing amplifier and to provide the first tri-state signal to a data bus line;
a second sensing amplifier to amplify data received from the memory array; and
a second driver to generate a second tri-state signal responsive to the amplified data from the second sensing amplifier, and to provide the second tri-state signal to the data bus line, where a first output loading on the first sensing amplifier as affected by the first driver is different from a second output loading on the second sensing amplifier as affected by the second driver, and where the first driver and the second driver provide a substantially equal load to the data bus line.

Abstract
A memory device includes a first sensing amplifier to amplify data received from the memory array, a first driver to generate a first tri-state signal responsive to the amplified data from an first sense amplifier and to provide the first tri-state signal to a data bus line, a second sensing amplifier to amplify data received from the memory array, and a second driver to generate a second tri-state signal responsive to the amplified data from an second sense amplifier and to provide the second tri-state signal to the data bus line, where the first sensing amplifier and the first driver are located in different regions of the device, and the second sensing amplifier and the second driver are located in a common region of the device.
