Abstract
In one embodiment, a method of performing an active polling operation can include: (i) detecting a self-timed operation that is to be executed on a serial memory device; (ii) determining if an active polling mode has been enabled; (iii) determining when the self-timed operation has completed execution on the serial memory device; and (iv) providing a completion indication external to the serial memory device when the self-timed operation has completed execution and the active polling mode is enabled.
Claims20
A serial memory device, comprising:
- a) a command decoder configured to detect a self-timed operation that is to be executed on the serial memory device;
- b) a mode detector comprising a plurality of bit match circuits, and being configured to detect when an active polling mode is enabled by matching a received opcode against a predetermined opcode via the plurality of bit match circuits, wherein the received opcode is serially clocked into the serial memory device one bit at a time;
- and
- c) an operation completion indicator configured to provide a completion indication external to the serial memory device when the self-timed operation has completed execution and the active polling mode is enabled.
A method of performing an active polling operation, the method comprising:
- a) detecting a self-timed operation that is to be executed on a serial memory device;
- b) determining if an active polling mode has been enabled by matching a received opcode against a predetermined opcode, wherein the received opcode is serially clocked into the serial memory device one bit at a time;
- c) determining when the self-timed operation has completed execution on the serial memory device;
- and
- d) providing a completion indication external to the serial memory device when the self-timed operation has completed execution and the active polling mode is enabled.
