Abstract:
The present application relates to the field of semiconductors, in particular, to the field of Dynamic Random Access Memories (DRAMs), and provides a method and system for detecting a mismatch of a sense amplifier. The method creates a sense amplifier by delaying switch-on of a positive channel-metal-oxide-semiconductor (PMOS) transistor or a negative channel-metal-oxide-semiconductor (NMOS) transistor in the sense amplifier and shortening a row precharge command period (tRP).
