    Abstract: Self-referenced, built-in access shutdown mechanism for a memory circuit. Instead of using a separate reference decoder/driver block and reference wordline path in the access timing loop, a wordline selected for accessing a core cell itself is utilized for referencing a shutdown sequence. A pair of complementary reference bitlines (BLS and BLE) are operable with a column of reference cells disposed in the row decoder. BLS/BLE control logic circuitry is operable to fine-tune the WL pulse width so as to minimize dead time and power consumption in access cycle operations.
