摘要:
Providing a serial array semiconductor architecture achieving fast program, erase and read times is disclosed herein. By way of example, a memory architecture can comprise a serial array of semiconductors coupled to a metal bitline of an electronic memory device at one end of the array, and a gate of a pass transistor at an opposite end of the array. Furthermore, a second metal bitline is coupled to a drain of the pass transistor. A sensing circuit that measures current or voltage at the second metal bitline, which is modulated by a gate potential of the pass transistor, can determine a state of transistors of the serial array. Because of low capacitance of the pass transistor, the serial array can charge or discharge the gate of the pass transistor quickly, resulting in read times that are significantly reduced as compared with conventional serial semiconductor array devices.
