Abstract
A data storage circuit for storing data from volatile memory in response to a power loss, the data storage circuit including an input for receiving a power loss signal in response to a power loss from at least one power source, an input configured to receive data from a volatile memory, a single block of non-volatile matrix of memory cells and a driver circuit coupled to said single row of non-volatile matrix of memory cells. The driver circuit is configured to write data to and read data from said single block of non-volatile matrix of memory cells. The single block of non-volatile matrix of memory cells can be provided as a single row electrically erasable programmable read only memory (EEPROM).
