Bus Training with Interconnected Dice - A simplified explanation of the abstract
This abstract first appeared for US patent application 17823423 titled 'Bus Training with Interconnected Dice
Simplified Explanation
The patent application describes apparatuses and methods for bus training with multiple dice, such as multiple memory dice. A controller communicates with the dice to perform bus training by sending a test pattern and receiving a feedback pattern indicating the detected bits. Individualized training may be infeasible, so logic associated with multiple dice can combine detected bits into a combined feedback pattern using logical operations. A timing parameter suitable for multiple dice is determined, and training is concluded when the combined feedback pattern matches the test pattern. The multiple dice may be stacked or linked.

Original Abstract Submitted
Described apparatuses and methods facilitate bus training with multiple dice, such as multiple memory dice. A controller can communicate with multiple dice to perform bus training by sending a test pattern and receiving in return a feedback pattern indicative of the bits detected by the dice. Because suitable signal timing can differ between dice, even those using the same bus, a controller may train each die separately from the others. In some situations, however, individualized training may be infeasible. To accommodate such situations, logic associated with two or more dice can combine, using at least one logical operation, bits as detected from the test pattern into a combined feedback pattern. A timing parameter that is jointly suitable for multiple dice can be determined, and the bus training may be concluded, responsive to the combined feedback pattern matching the test pattern. The multiple dice may be stacked or linked.
