ENABLE SIGNAL GENERATING CIRCUIT FOR LOCAL INPUT/OUTPUT SENSE AMPLIFIER AND ENABLE SIGNAL GENERATING CIRCUIT FOR INPUT/OUTPUT SENSE AMPLIFIER IN SEMICONDUCTOR MEMORY DEVICE

摘要

Purpose: it is arranged to have exploitation one local I/O lines pair side and one global I/O lines to by controlling enabling time according to frequency for the enabling signal generating circuit for being used for local I/O (input/output) sense amplifier of an input/output sense amplifier and an enabling signal generating circuit. Construction: signal generating circuit, including tDAC records (34) are enabled for providing tDAC information for one of local I/O (input/output) sense amplifier in semiconductor storage device; One postpones device (32), is used to receive a column latch signal (collating), write-in signal (writing) and an output signal from tDAC and for exporting and enables signal (PLIOSE) for local I/O sense amplifiers one. Signal generating circuit, including tDAC records are enabled for providing tDAC information for one of the input/output sense amplifier in semiconductor storage device; One postpones device, is used to receive a tower cycle signal (COLCYC), write-in signal (writing) and an output signal from tDAC and for exporting enabling signal (PIOSE) for being used for input/output sense amplifier.
