ABSTRACT:
A clock generator is used in a non-volatile memory to generate a timing signal for clocking a sense amplifier. The timing signal duration is timed using circuit features which also affect the rate with which data can be sensed by the sense amplifier. The clock generator includes a reference word line which is analogous to an accessed word line, a memory cell which establishes a reference current analogous to that provided by an accessed cell, and a current mirror which uses the reference current to charge a reference line analogous to a bit line. The duration of the timing signal is established by the reference line reaching a predetermined voltage.
