Abstract
A sense amplifying circuit includes a replica circuit including one or more active resistors coupled in series between a ground voltage node and a first node; a current control circuit configured to supply a keeper current to a sensing node coupled to at least one memory cell when a sensing enable signal is activated, and to control an amount of the keeper current based on a voltage level of the first node; and a sensing circuit configured to sense and output a voltage at the sensing node.
