Non-volatile memory data retention using system RAM and SSD

A method comprising:

• receiving, from a cabinet input electrical power source in an electronic game machine, a charging current into a battery charging circuit to provide a charging current to a battery;
• receiving, into a processor circuit, an indication that the cabinet input electrical power source has failed;
• in response to receiving the indication that the cabinet input electrical power source has failed, halting functional operations of an electronic game machine;
• in response to the functional operations being halted, operations comprise copying machine operating data from a first memory comprising a first memory type to a second memory comprising a second memory type;
• and
• in response to the copying being complete, disabling a back-up voltage supply that is provided by the battery,
• wherein the first memory and the second memory are powered by the battery for the second memory to receive the operating memory instructions from the first memory after the first switching power has failed, and
• wherein, responsive to the controller receiving a transfer compete indication corresponding to the operating memory instructions being moved to the second memory, causing the power switching circuit to switch from the second switching power input to the first switching power input.

A system comprising:

• a processor circuit;
• a battery charging circuit that is conductively coupled to a cabinet input power source and that provides a charging current to a battery;
• a power switching circuit that comprises a first switching power input that corresponds to the cabinet input power source, a second switching power input corresponding to the battery, and a power state output signal that is transmitted to the processor circuit and that comprises a value that depends on the first switching power input;
• a controller that receives, from the processor circuit, an interrupt signal that indicates that first switching power has failed and transmits a switch signal to the power switching circuit that is caused to switch from providing power from the cabinet input power source to providing power from the battery;
• a RAM memory that comprises operating memory instructions;
• a solid state drive that is configured to receive operating memory instructions from the RAM memory responsive to the interrupt signal indicating that the first switching power has failed, the solid state drive being caused to avoid writing to solid state drive memory when a host electronic game machine is operating;
• and
• a boost power converter that provides the second switching power input from the battery and based on the controller,
• wherein a first memory and a second memory are powered by the battery for the second memory to receive the operating memory instructions from the first memory after the first switching power has failed, and
• wherein, responsive to the controller receiving a transfer compete indication corresponding to the operating memory instructions being moved to the second memory, causing the power switching circuit to switch from the second switching power input to the first switching power input.
