Erase suspend scheme in a storage device

A method of operating a storage device, comprising:

• performing, by a non-volatile memory, an erase operation on a block of memory in the non-volatile memory, wherein the non-volatile memory is coupled to a controller;
• receiving, by the non-volatile memory, a host-transaction within a first time period, wherein the non-volatile memory is coupled to a host device;
• and
• suspending, by the non-volatile memory in response to receiving the host-transaction, an erase operation by:
• determining the erase operation has completed a charge phase;
• and
• suspending the erase operation during a pulse phase of the erase operation.

A system comprising:

• a host;
• a memory coupled to the host, the memory comprising:
• a memory array;
• and
• control circuits configured to access the memory array;
• a controller coupled to the memory, wherein the controller operates as an interface between the host and the memory, wherein the controller is configured to:
• transmit an erase command to a first block of cells within the memory array, wherein the erase command is performed in a first time period;
• and
• transmit a transaction request to the memory array within the first time period, wherein the memory is configured to:
• in response to the erase command, initiate an erase operation on the first block of cells;
• in response to the transaction request, suspend the erase operation and service the transaction request;
• and
• determine a charge phase of the erase operation is complete when the memory suspends the erase operation in response to the transaction request.
