1. An apparatus, comprising:
a memory cell in electronic communication with a bit line;
a current generator coupled with the bit line and operable to charge the bit line to a voltage level by applying a variable current; and
a controller coupled with the memory cell and the current generator, the controller operable to identify a logic state of the memory cell based at least in part on applying the variable current.
