Provided are a method and apparatus for performing error handling operations using error signals A first error signal is asserted on an error pin on a bus to signal to a host memory controller that error handling operations are being performed by a memory module controller in response to detecting an error. Error handling operations are performed to return the bus to an initial state in response to detecting the error. A second error signal is asserted on the error pin on the bus to signal that error handling operations have completed and the bus is returned to the initial state.

Method and apparatus for performing error handling operations using error signals

Provided are a device and computer readable storage medium for programming a memory module to initiate a training mode in which the memory module transmits continuous bit patterns on a side band lane of the bus interface; receiving the bit patterns over the bus interface; determining from the received bit patterns a transition of values in the bit pattern to determine a data eye between the determined transitions of the values; and determining a setting to control a phase interpolator to generate interpolated signals used to sample data within the determined data eye.

Read training a memory controller

A memory controller transmits a control signal to a memory module, where the memory controller continuously transmits a clock signal to the memory module. The memory controller determines adjustments to the control signal with respect to the clock signal, by iteratively analyzing a strobe signal.

Method for training a control signal based on a strobe signal in a memory module

A mechanism is described for achieving high memory reliability, availability, and serviceability (RAS) according to one embodiment of the invention. A method of embodiments of the invention includes detecting a permanent failure of a first memory device of a plurality of memory devices of a first channel of a memory system at a computing system, and eliminating the first failure by merging a first error-correction code (ECC) locator device of the first channel with a second ECC locator device of a second channel, wherein merging is performed at the second channel.

Mechanism for achieving high memory reliablity, availability and serviceability

An example computer system includes a first bridge device that includes an interface controller. The interface controller combines debug information generated within the bridge device with a training pattern. The first bridge device is coupled to a second bridge device via a high-speed asynchronous interconnect. The first bridge device converts the debug information and training pattern into a packet to be transmitted over the interconnect to the second bridge device. The training pattern serves to allow the second bridge device to maintain bit and symbol synchronization during the transfer; of the debug information.
