| 摘要 |
A dual mode memory module includes an interface configured to receive a first memory module, a first control circuit for switching between unbuffered and registered/buffered modes, an interface configured to receive a second memory module, and a second control circuit for switching the operation of the second memory module between unbuffered and registered/buffered modes. The control circuit may include a bus switch and a register/buffer operatively coupled to the bus switch. Enable/disable pins may be included operatively coupled to the first bus switch and the first register/buffer and configured so that only one of the first bus switch and the first register/buffer is active at a time. A system controller for detecting a type of memory module connected to the stackable dual mode memory interface and enabling one of the bus switch and register/buffer based on the type of memory module detected may be included.</PTEXT>
