ADVANCED BIT LINE TRACKING IN HIGH PERFORMANCE MEMORY COMPILERS

摘要

memory compiler for the bit line maturity (maturing) for how to time the exact tracking is presented. The method includes an enable (enable) to step in response to the internal clock signal of the dummy (dummy) word lines. The dummy word line is enabled prior to enabling a real word line. Dummy bit line is enabled in response to the maturation of the dummy word line. The dummy bit line is mature at the same rate of the real bit line matures. The method also includes the step of disabling the dummy word line in response to a determination of the threshold voltage difference based on the monitoring of the maturation of a dummy bit line. The actual word line is enabled after a predefined delay than the enable of the dummy word line. Similarly, the word line is disabled after a pre-defined than disabling the dummy word line delay. In response to disabling the dummy word lines, sense enable signal is generated. ;
