Abstract:
1. A method for measuring characteristics of a storage array, said method comprising: propagating a wordline select pulse along a wordline select signal path of a row circuit of said storage away to an output driver circuit; delaying said wordline select pulse by using a access detection cell that holds an input of said output driver circuit until a simulated access operation activated by said pulse has completed in said access detection cell, wherein the delaying is performed by presetting a state of an inverter in said access detection cell in response to an inactive state of said wordline select signal using a preset circuit, disabling said preset circuit in response to said pulse, and forcing an output of said inverter in response to said pulse through a pass transistor connected to said output of said inverter, whereby said output of said inverter has a loading equivalent to that of an input of said inverter to simulate a access to a storage cell of said storage array.
