Adaptive memory system for enhancing the performance of an external computing device

An adaptive memory system is provided for improving the performance of an external computing device. The adaptive memory system includes a single controller, a first memory type (e.g., Static Random Access Memory or SRAM), a second memory type (e.g., Dynamic Random Access Memory or DRAM), a third memory type (e.g., Flash), an internal bus system, and an external bus interface. The single controller is configured to: (i) communicate with all three memory types using the internal bus system; (ii) communicate with the external computing device using the external bus interface; and (iii) allocate cache-data storage assignment to a storage space within the first memory type, and after the storage space within the first memory type is determined to be full, allocate cache-data storage assignment to a storage space within the second memory type.
