Abstract:
Techniques for implementing a hybrid non-volatile memory storage system are disclosed. The hybrid memory system may include a first non-volatile memory; a second non-volatile memory; and a memory controller to analyze a type of an operation and a characteristic of the operation, to determine a state of the second non-volatile memory, and to determine whether another operation is being implemented on the second non-volatile memory, the memory controller selectively implementing an operation on one of the first non-volatile memory and the second non-volatile memory segment based on the type of the operation, the characteristic of the operation, the state of the second non-volatile memory, and whether another operation is being implemented on the second non-volatile memory such that the memory controller implements the operation on the first non-volatile memory concurrently with the other operation being implemented on the second non-volatile memory based on the type of the operation.
