receiving a read request at the memory controller;

determining whether the read request can be serviced faster by temporarily canceling a request to set the cells of a memory line to a specified state;

canceling the request to set the cells of the memory line to a common specified state responsive to determining that the read request can be serviced faster by temporarily canceling a request to set the cells of the memory line to a common specified state; and

reinitiating the request to set the cells of the memory line to a common specified state responsive to the canceling and to a completion of the read request.
