Abstract
A compact and versatile sense amp is presented. Among its other features this sense amp arrangement provides a way to pre-charge bit lines while doing data scanning. Another feature is that the sense amp circuit can provide a way to set three different bit line levels used in the quick pass write (QPW) technique using dynamic latch, where quick pass write is a technique where cells along a given word line selected for programming can be enabled, inhibited, or partially inhibited for programming. Also, it can provide a convenient way to measure the cell current.
