Abstract
A bridge device architecture for connecting discrete memory devices. The bridge device is used in conjunction with a composite memory device including at least one discrete memory device. The bridge device includes a local control interface for connecting to the at least one discrete memory device, a local input/output interface for connecting to the at least one discrete memory device, and a global input/output interface interposed between the local control interface and the local input/output interface. The global input/output interface receives and provides global memory control signals and also receives and provides write data to and read data from the at least one discrete memory device.
Claims28
A bridge device to access a discrete memory device, the bridge device comprising:
- a first local interface communicating a first portion of local signals between the bridge device and the discrete memory device;
- a second local interface communicating a second portion of local signals between the bridge device and the discrete memory device;
- and,
- a global input/output interface interposed between the first local interface and the second local interface, the global input/output interface communicating global signals to and from the bridge device.
A composite memory device comprising:
- at least one discrete memory device for executing memory operations in response to local memory control signals having a local format, and
- a bridge device comprising:
- a first local interface communicating a first portion of local signals between the bridge device and the at least one discrete memory device;
- a second local interface communicating a second portion of local signals between the bridge device and the at least one discrete memory device;
- and,
- a global input/output interface interposed between the first local interface and the second local interface, the global input/output interface communicating global signals to and from the bridge device.
A memory system comprising:
- a memory controller for providing a global command corresponding to a memory operation;
- and
- N composite memory devices connected serially with each other and the memory controller in a ring topology configuration, each of the N composite memory devices having M discrete memory devices and a bridge device, each bridge device comprising a first local interface communicating a first portion of local signals between the bridge device and at least one of the M discrete memory devices, a second local interface communicating a second portion of local signals between the bridge device and the at least one of the M discrete memory devices, and, a global input/output interface interposed between the first local interface and the second local interface, the global input/output interface communicating global signals to and from the bridge device, where N and M are integer values greater than 0.
