Abstract

A driver for a semiconductor memory includes: a selection controller configured to output a target charge current select signal and a bucket charge current select signal in response to an inputted memory cell address and a target charge current value and a bucket charge current value, which are to be applied to a memory cell of the memory cell address; a current supply unit configured to supply a target charge current to the memory cell of the memory cell address in response to the target charge current select signal; and a bucket charge current supply unit configured to supply a bucket charge current to the memory cell of the memory cell address, in order to pre-charge the memory cell of the memory cell address in response to the bucket charge current select signal.
