Memory devices for suspend and resume operations

A memory device comprising:

• an array of memory cells;
• and
• a controller configured to access the array of memory cells,
• wherein the controller is further configured to:
• receive a command to perform an erase operation;
• in response to the command to perform the erase operation, begin execution of the erase operation;
• in response to executing the erase operation, pull down a ready/busy control signal to indicate the memory device is busy executing the erase operation;
• while executing the erase operation, receive a command to perform a read operation with the ready/busy control signal pulled down;
• in response to the command to perform the read operation, suspend the execution of the erase operation while keeping the ready/busy control signal pulled down;
• and
• with the execution of the erase operation suspended and with the ready/busy control signal pulled down, execute the read operation while keeping the ready/busy control signal pulled down.

A memory device comprising:

• an array of memory cells;
• and
• a controller configured to access the array of memory cells,
• wherein the controller is further configured to:
• receive a command to perform a program operation;
• in response to the command to perform the program operation, begin execution of the program operation;
• receive a command to suspend the execution of the program operation;
• in response to the command to suspend the execution of the program operation, suspend the execution of the program operation;
• with the execution of the program operation suspended, receive a command to perform a read operation;
• in response to the command to perform the read operation, execute the read operation;
• in response to executing the read operation, pull down a ready/busy control signal to indicate the memory device is busy executing the read operation;
• and
• in response to the execution of the read operation completing and with the ready/busy control signal pulled down, resume the execution of the program operation while keeping the ready/busy control signal pulled down.
