Synchronous flash memory with accessible page during write

A method of operating a flash memory comprising:

• copying first data stored in a first row of a first array bank to a buffer circuit using control circuitry of the flash memory in response to a command from an external processor coupled to the flash memory;
• performing a write operation to write second data to a second row of the first array bank using the external processor in response to a write command provided by the processor;
• reading the first data from the buffer circuit using the external processor while performing the write operation in response to a read command provided by the processor, wherein the first data contains instruction code for the external processor;
• and
• monitoring a status register of the flash memory with the external processor in response to the instruction code.

A method of operating a flash memory comprising:

• receiving a write command at the flash memory, wherein the write command is provided by an external processor coupled to the flash memory;
• automatically copying first data stored in a first row of a first array bank to a buffer circuit using control circuitry of the flash memory in response to the write command;
• performing a write operation to write second data to a second row of the first array bank using the external processor in response to a write command provided by the processor;
• reading the first data from the buffer circuit using the external processor while performing the write operation in response to a read command provided by the external processor, wherein the first data contains instruction code for the external processor;
