Abstract

A memory module can include a hybrid media controller coupled to a volatile memory, a non-volatile memory, a non-volatile memory buffer and a set of memory mapped input/output (MMIO) register. The hybrid media controller can be configured for reading and writing data to a volatile memory of a memory mapped space of a memory module. The hybrid media controller can also be configured for reading and writing bulk data to a non-volatile memory of the memory mapped space. The hybrid media controller can also be configured for reading and writing data of a random-access granularity to the non-volatile memory of the memory mapped space. The hybrid media controller can also be configured for self-indexed moving data between the non-volatile memory and the volatile memory of the memory module.

Claims23

Dependent claims

A memory module comprising:

a volatile memory;
a non-volatile memory;
a non-volatile memory buffer;
a set of memory mapped input/output (MMIO) registers;
an interface;
and
a hybrid media controller, wherein the hybrid media controller comprises:
a non-volatile memory read/write controller coupled to the non-volatile memory, the set of MMIO registers and the non-volatile memory buffer;
a volatile memory read/write controller coupled to the volatile memory and the set of MMIO registers;
a flow controller coupled to the non-volatile memory read/write controller, the volatile memory read/write controller and the set of MMIO registers;
and
an address generator coupled to the volatile memory read/write controller and the set of MMIO registers, and wherein the hybrid media controller is configured to provide:
read and write access to the volatile memory;
bulk read and write access to the non-volatile memory;
read and write random access to the non-volatile memory;
and
self-indexed data movement between the non-volatile memory and the volatile memory.

A method of accessing data comprising:

reading and writing data to a volatile memory of a memory mapped space of a memory module;
reading and writing bulk data to a non-volatile memory of the memory mapped space of the memory module;
reading and writing data of a random access granularity to the non-volatile memory of the memory mapped space;
and
moving self-indexed data between the non-volatile memory and the volatile memory of the memory module,
wherein reading and writing data to the volatile memory of the memory mapped space includes:
receiving a volatile memory address and a random access read operation into a set of memory mapped input/output (MMIO) registers of the memory mapped space;
reading data of a random access granularity from the volatile memory at the volatile memory address in the set of MMIO registers by a hybrid media controller in response to the random access read operation in the set of MMIO registers;
and
setting by the hybrid media controller a read data status in the set of MMIO registers.
