Abstract:
1. A single type latch-based write driver control circuit for controlling an operation of a write driver, which amplifies and transmits data of a pair of global input/output lines to a pair of local input/output lines in a write operation, the single type latch-based write driver control circuit comprising: a single type latch section, in a write operation, configured to compare states of first and second data of the pair of global input/output lines having been differentially inputted in a first status and then outputting a first output signal to a first output node, comparing states of the first and second data having been differentially inputted in a second status and then outputting a second output signal to a second output node, and continuously latching states of the first and second output nodes before a precharge operation starts; a precharge controller configured to equalize and precharge the first and second output nodes in the precharge operation; and an output section configured to output first and second driver signals and first and second latch signals configured to control a write driver, by using the first and second output signals.
