US 2019/0196961 A1 · Flash Medium Access Method and Controller

Abstract

A flash medium access method, including selecting, by a controller, a target function queue from N function queues according to a predefined rule, where the target function queue is a non-empty queue, a flash medium in which a die associated with the target function queue is located is in an idle state, obtaining a basic instruction from the target function queue, determining, according to preset queue mapping information, the die associated with the target function queue, where the controller is connected to at least one flash medium, and the queue mapping information indicates that the N function queues are in a one-to-one mapping relationship with the N dies, generating, according to a preset signal generation rule, a time sequence signal corresponding to the basic instruction, and sending the time sequence signal to the flash medium in which the associated die is located.

Dependent claims

A flash medium access method, comprising:

selecting, by a controller, a target function queue from a plurality of function queues, wherein the target function queue is a non-empty queue, wherein a flash medium in which a die associated with the target function queue is located is in an idle state, wherein the controller is coupled to at least one flash medium, wherein each of the at least one flash medium comprises at least one die, wherein mashes of function queues is a same as a number of dies in each flash medium;
obtaining, by the controller, a basic instruction from the target function queue;
identifying, by the controller according to queue mapping information, the die associated with the target function queue, wherein the queue mapping Information indicates a mapping relationship between the function queues and the dies;
generating, by the controller according to a signal generation rule, a time sequence signal corresponding to the basic instruction:
and
sending, by the controller, the time sequence signal to the flash medium in which the associated die is located.

A controller, comprising:

a memory configured to store a plurality of instructions;
and
a processor coupled to the memory, wherein the instructions cause the processor to be configured to:
select a target function queue from a plurality of function queues, wherein the target function queue is a non-empty queue, wherein a flash medium in which a die associated with the target function queue is located is in an idle state, wherein the controller is coupled to at least one flash medium, wherein each of the at least one flash medium comprises at least one die, and wherein a number of function queues is as a number of dies;
obtain a basic instruction from die target function queue;
identify, according to queue mapping information, the die associated with the target function queue, wherein the queue mapping information indicates a mapping relationship between the function queues and the dies;
generate, according to a signal generation rule, a time sequence signal corresponding to the basic instruction;
and
send the time sequence signal to the flash medium in which the associated die is located.

6 more elements

A computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to:

select a target function queue from a plurality of function queues, wherein the target function queue is a non-empty queue, wherein a flash medium in which a die associated with the target function queue is located is in an idle state, wherein the controller is coupled to at least one flash medium, wherein each of the at least one flash medium comprises at least one die, and wherein a number of function queues is same as a number of dies;
obtain a basic instruction from the target function queue;
identify, according to queue mapping information, the die associated with the target function queue, wherein the queue mapping information indicates a mapping relationship between the function queues and the dies;
generate, according to a signal generation rule, a time sequence signal corresponding to the basic instruction;
and
send the time sequence signal to the flash medium in which the associated die is located.
