METHOD AND APPARATUS FOR PERFORMING ERROR HANDLING OPERATIONS USING ERROR SIGNALS

摘要

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.

1. An apparatus in communication with a host memory controller over a bus, comprising:
a memory module controller of a memory module to:
assert a first error signal on an error pin on the bus to signal to the host memory controller that error handling operations are being performed by the memory module controller in response to detecting an error;perform error handling operations to return the bus to an initial state in response to detecting the error; andassert a second error signal on the error pin on the bus to signal that error handling operations have completed and the bus is returned to the initial state.
