Systems, methods, and other embodiments associated with conserving power using variable width pulses to activate word lines are described. In one embodiment, a memory device embedded within a processor. The memory device includes a pulse shaper to generate a first timing delay and a second timing delay according to power state information. The power state information indicates a current operating state of the processor. The memory device includes a memory controller to generate, in response to receiving a request to access one or more memory cells of the memory device, a word line enable signal that activates the one or more memory cells according to the first timing delay, the second timing delay, and a clock signal by generating the word line enable signal with a pulse width that is variable to conserve power when the state information indicates the processor is in a power saving state.
