Electronic system for adaptively adjusting allocation of memory area and method of operating the electronic system

A method of operating an electronic system including a plurality of functional blocks and a main memory, the method comprising:

• receiving an alternative mode entry command requesting entry to the alternative mode while a first area of the main memory is allocated to a first functional block of the plurality of functional blocks;
• loading first boot data corresponding to the alternative mode;
• re-booting the main memory by executing the first boot data;
• and
• re-allocating the first area of the main memory allocated to the first functional block to a second functional block of the plurality of functional blocks after rebooting the main memory.

An electronic system comprising:

• an input device configured to receive an input;
• a plurality of functional blocks each configured to perform operations according to a user request, the plurality of functional blocks including a first functional block and a second functional block;
• a boot data memory configured to store first boot data and second boot data, the first boot data corresponding to an alternative mode and the second boot data corresponding to a standard mode;
• a main memory including a first area and a second area, the first area associated with driving the first functional block and the second area associated with driving the second functional block;
• and
• a processor configured to,
• boot the electronic system using one of the first boot data and the second boot data based on an operation mode, and
• adjust a ratio of a memory area of the first area and the second area by re-booting the electronic system using the first boot data, in response to the input device receiving an alternative mode entry command from the user.
