Abstract
A memory device includes a plurality of memory cells, a token input interface, a token output interface and control circuitry. The control circuitry is configured to accept a storage command, to condition execution of at least a part of the storage command on a presence of a token pulse on the token input interface, to execute the storage command, including the conditioned part, in the memory cells upon reception of the token pulse on the token input interface, and to reproduce the token pulse on the token output interface upon completion of the execution.
Claims14
A memory device, comprising:
- a plurality of memory cells;
- a token input interface;
- a token output interface;
- and
- control circuitry coupled between the token input interface and the token output interface, wherein the control circuitry is configured to conditionally execute a received storage command dependent on a presence of a token pulse on the token input interface, wherein the token pulse enables execution of at least some storage commands, wherein in response to the presence of the token pulse the control circuitry is configured to execute the storage command in the memory cells, and to reproduce the token pulse on the token output interface upon completion of the execution.
A method, comprising:
- accepting a storage command in a memory device that includes a plurality of memory cells;
- conditionally executing the received storage command dependent on a presence of a token pulse on a token input interface of the memory device, wherein the token pulse enables execution of at least some storage commands;
- executing the storage command in response to the presence of the token pulse on the token input interface;
- and
- reproducing the token pulse on a token output interface of the memory device upon completion of the execution.
