摘要:
An integrated circuit includes: a terminal for outputting data, a driver for providing the data to the terminal, and a switch for selectively connecting/disconnecting the driver to the terminal. The disconnection of the driver reduces the capacitive load on the connection between the terminal and driver, thus reducing limitations on data rate from factors such as data reflections that reduce signal quality. Selective connection/disconnection allows the driver to be reconnected to the terminal only when needed.

A memory system is functionally designed so that, despite operation without an error correction device, memory chips of a memory module that are actually provided for error correction are concomitantly used for the data transfer. A control device is configured to receive, store and transfer data packets to and from a first and second set of memory chips. Transfer of an internal packet data from the control device to memory takes place such that a first record is stored in a second set of memory chips and additional records are stored in the first set of memory chips. In preferred embodiments, data is allocated in the second set of memory chips such that at least one additional transfer step takes place to the second set of memory chips compared with transfers to the first set of memory chips. In the additional transfer step(s), the first set of memory chips is masked from receiving data.

A semiconductor memory system is disclosed. In one embodiment, the semiconductor memory system and memory module of the present invention provides a buffer, wherein at least one write buffer chip on the memory module is only buffering and registering write data, command and address signals written from a memory controller to the memory chips. As read data are written back from each memory chip directly to the memory controller through unidirectional point-to-point read data lines the present semiconductor memory system achieves a low latency as compared with a fully buffered DIMM concept. As read data are only unidirectional a high transmission bandwidth can be achieved.
