Abstract
A hierarchical memory storage using a concentrator device that is located between a processor and memory storage devices to provide an interface to accommodate different memory formats.
Claims23
A concentrator device to channel data from a processor that is received at a frontside port to memory storage devices coupled to a backside port, where the concentrator device stores the received data in a Phase Change Memory (PCM) and provides an interface to the memory storage devices having different memory formats.
A concentrator device having a backside port to couple a NAND memory to an internal NAND interface, comprising:
- a Phase-Change Memory (PCM);
- a page buffer to hold data for storage in the PCM;
- a command queue;
- and
- a NAND state machine to execute a command to control the internal NAND interface and adjust data input and/or output at the backside port with the page buffer based on the command.
A concentrator device, comprising:
- first and second backside ports to couple external memory devices having differing storage mechanisms and different interface formats;
- a Phase-Change Memory (PCM);
- a page buffer to receive data at a frontside port to hold for storage in the PCM;
- and
- a NAND state machine to execute a command to control an internal NAND interface and adjust data input and/or output at the backside port with the page buffer based on the command.
A system, comprising:
- a dual core processor having a frontside bus;
- a mass storage memory;
- and
- a concentrator device having a frontside port coupled to the frontside bus to channel data from the processor to the mass storage memory that is coupled to a backside port, where the concentrator device stores data in a Phase Change Memory (PCM) and provides an interface to the mass storage memory.
A memory storage system, comprising:
- a first concentrator device to store data from a processor received at a frontside port in a Phase Change Memory (PCM) and provide an interface to memory storage devices having different memory formats coupled to a backside port;
- and
- a second concentrator device to receive data at a frontside port from the first concentrator device, store the data in a Phase Change Memory (PCM) that is transferred to additional memory storage devices coupled to a backside port.
A memory storage system, comprising:
- a concentrator device to receive addresses at a frontside port in a Phase Change Memory (PCM) and use a discovery process to determine types of memory that are attached to a backside port.
