Abstract:
1. In an interface circuit of a data storage system, a point-to-point channel directly connecting to both the interface circuit and a volatile memory cache circuit, a method for exchanging data with the volatile memory cache circuit, the method comprising the steps of: providing a command to the volatile memory cache circuit through the point-to-point channel which directly connects to both the interface circuit and the volatile memory cache circuit, the point-to-point channel including a first link and a second link; dividing a data element into a first half of the data element and a second half of the data element; moving the data element through the point-to-point channel in accordance with the command, the step of moving including the step of conveying the first half of the data element through the first link and the second half of the data element through the second link, the step of conveying including the step of transmitting the first half of the data element from a first transmitter and concurrently transmitting the second half of the data element from a second transmitter; and receiving status from the volatile memory cache circuit through the point-to-point channel in accordance with the data element.
