ABSTRACT:
A dynamic slew rate controlling method and a device is provided to reduce SSO variance generated from voltage noises, which is as a result of a plurality of data bits switching to the same state simultaneously while the I/O bus transmits these data bits. The device and method at first analyzes data patterns, then determines the slew rate controlling setting value based on the slew rate controlling mapping table corresponding to different data patterns, and then transmits the setting value to the I/O buffer with the same voltage level in order to reduce the SSO variance.
