Abstract
Method and apparatus for amplifying a signal (50) to produce a latched digital signal (46). In one embodiment, an output stage circuit (24) of memory (10) includes a differential amplifier circuit (100), a level converter (102), a timing circuit (104), a clock-free latch (106), a high impedance control circuit (108), a high impedance control circuit (110), and an output driver (112). Output stage (24) requires one clock signal to function. Alternate embodiments may skew the disabling edge of the clock to improve the speed characteristics of output stage (24). In one embodiment, signal (50) is a differential pair of signals provided from a memory bit cell array (12).
