Abstract
A memory subsystem is disclosed. The memory subsystem includes a serial peripheral interface (SPI) double data rate (DDR) volatile memory component, a serial peripheral interface (SPI) double data rate (DDR) non-volatile memory component coupled to the serial peripheral interface (SPI) double data rate (DDR) volatile memory component and a serial peripheral interface (SPI) double data rate (DDR) interface. The serial peripheral interface (SPI) double data rate (DDR) interface accesses the serial peripheral interface (SPI) double data rate (DDR) volatile memory component and the serial peripheral interface (SPI) double data rate (DDR) non-volatile memory component where data is accessed on leading and falling edges of a clock signal.
