    摘要: A system and method utilize a memory device that may be accessed by a plurality of controllers or processor cores via respective ports of the memory device. Each controller may be coupled to a respective port of the memory device via a data bus. Each port of the memory device may be associated with a predefined section of memory, thereby giving each controller access to a distinct section of memory without interference from other controllers. A common command/address bus may couple the plurality of controllers to the memory device. Each controller may assert an active signal on a memory access control bus to gain access to the command/address bus to initiate a memory access. In some embodiments, a plurality of memory devices may be arranged in a memory package in a stacked die memory configuration.

    摘要: A memory system includes a number of integrated circuit chips coupled to a bus. Each of the integrated circuit chips has an input/output node coupled to the bus, the input/output node having a programmable on-die termination resistor. The input/output node of one of the integrated circuit chips is accessed via the bus. The programmable on-die termination resistor of each of the integrated circuit chips is independently set to a termination resistance. The termination resistance is determined by a transaction type and which of the plurality memory devices is being accessed, which information can be transmitted over a separate transmission control bus.
