Abstract

In one non-limiting embodiment, a method is disclosed for performing a storage device operation on a die is provide having steps of choosing a storage device operation to perform, estimating which die is related to the storage device operation chosen to be performed and performing the storage device operation at the die based on the estimating.

Claims (18)

1. A method for performing a storage device operation on a die, comprising:

choosing a storage device operation to perform;

estimating which die is related to the storage device operation chosen to be performed based on a look-up table and a formula using a die alignment, a logical based address and a die count; and

performing the storage device operation at the die based on the estimating.

2. The method according to claim 1 , wherein the storage device operation is a write operation.

3. The method according to claim 1 , wherein the estimating is additionally performed on an assumption of sequential operations of dies.

4. The method according to claim 1 , wherein the formula is:

commandDie=(((commandLBA−firstLba)/dieAlignment)+firstDie) % dieCount.

5. A method for performing a storage device operation on a die, comprising:

choosing a storage device operation to perform;

estimating which die is related to the storage device operation chosen to be performed based on a look-up table and a formula; and

checking a die estimated for the storage device operation to determine an idle state.

6. The method according to claim 5 , further comprising:

sending instructions for the storage device operation at the die to be executed when the die estimated for the storage device operation is scheduled to be idle.

7. The method according to claim 5 , further comprising:

waiting to send instructions for the storage device operation at the die estimated for the storage device operation when the die estimated for the storage device operation is not idle.

8. The method according to claim 5 , wherein the storage device operation is a read operation.

9. The method according to claim 5 , wherein the estimating of the die is also based on a table of starting logical based addresses and ending logical based addresses and page numbers.
