Abstract

A method and strobe circuit are provided for maintaining a strobe signal at a valid voltage level. The method includes driving the strobe signal at the valid voltage level using a first strobe driver, pre-driving the strobe signal at the valid voltage level using a second strobe driver while the first strobe driver is driving, and terminating the driving of the first strobe driver. The strobe circuit includes a strobe line, a first strobe driver having a first enable input for enabling the first strobe driver and adapted to drive the strobe line with a first strobe signal, and a second strobe driver having a second enable input for enabling the second strobe driver and adapted to drive the strobe line with a second strobe signal. A first strobe controller is coupled to the second enable input and adapted to enable the second strobe driver to pre-drive the second strobe signal while the first strobe driver is enabled, wherein the first and second strobe signals are at equal logic levels.
