Abstract
In certain embodiments, a method and apparatus for adjusting the timing of a sense-amplifier read operation in an SRAM integrated memory circuit to overcome process-and-temperature variations are disclosed. A charge-injection pull-up transistor is provided to adjust the rate at which a signal line (e.g., a tracking bit line (TBL) and/or a clock signal (e.g., GCLKB)) transitions from one voltage level to another voltage level. A process-and-temperature-dependent bias circuit is provided to control the charge-injection pull-up transistor. The bias circuit causes the charge-injection pull-up transistor to adjust the discharge rate or transition rate of the signal line to compensate for timing delays caused by process or temperature variations.
