1. A memory circuit, comprising:
- a memory cell configured to provide a charge, voltage, or current to an associated bit-line;
a sense amplifier configured to sense the charge, voltage, or current on the bit-line;
a word-line circuit configured to control a word-line of the memory cell;
a bit-line circuit having at least one of (i) a bit-line voltage control circuit and (ii) a mux circuit; and
a tracking circuit configured to track one or more conditions of the memory circuit and provide a timing control signal at an output operative to adaptively control at least one of;
(i) the word-line circuit, and (ii) bit-line circuit.

11. A memory circuit, comprising:
-
a memory cell configured to provide a charge, voltage, or current to an associated bit-line; a word-line circuit configured to control a word-line of the memory cell; a bit-line circuit having at least one of (i) a bit-line voltage control circuit and (ii) a mux circuit; and a sense amplifier comprising a local sense amplifier bias circuit, wherein the sense amplifier is configured to sense the charge, voltage, or current on the bit-line and locally control its local sense amplifier bias circuit by turning the local sense amplifier bias circuit OFF or placing it in low power state, upon determining that the charge, voltage, or current on the bit-line is above a predetermined threshold.

12. A method of controlling a memory circuit including a memory cell configured to provide a charge, voltage, or current to an associated bit-line, a bit-line circuit, a sense amplifier configured to sense the charge, voltage, or current on the bit-line, a word-line circuit configured to control a word-line of the memory cell, and a tracking circuit, the method comprising:
-
tracking one or more conditions of the bit-line of the memory circuit by the tracking circuit; and providing a timing control signal to at least one of (i) the word-line circuit and (ii) bit-line circuit of the memory circuit to adaptively control the word-line circuit based on the tracking. - View Dependent Claims (13, 14, 15, 16, 17, 18)
