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.

The invention describes a semiconductor memory module unit for P2P data interchange with a memory controller. Memory chips having different data widths can be arranged on the semiconductor memory module unit in such a way as to enable a tree-like branching by signal data transmission from a node-like memory chip to a plurality of downstream memory chips while retaining the data width.

A semiconductor memory module includes a wiring board in or on which at least a number of data line runs are conducted in a respective width of k bits and which exhibits a number of memory ranks which in each case have n memory chips, and at least one signal driver/control chip (hub), a k-bit-wide data line run in each case connecting a memory chip from each memory rank to the signal driver/control chip (hub) and four or eight memory ranks in each case being arranged distributed on the top and bottom of the wiring board along the associated data line run in such a manner that, in operation, the load is distributed along the respective data line run.
摘要:
An internal clock signal of a logic/memory component that receives signals is transmitted as a reference clock to a transmitting logic/memory component. With the aid of the reference clock, the transmission clock of the output unit of the transmitting logic/memory component is generated, such that transmitted signals arrive in a receiving unit of the receiving component synchronously with the internal clock signal of that component.
摘要:
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 memory apparatus includes at least two memory devices, each memory device including at least one memory bank. A method of operating the memory apparatus includes receiving a row activation command generated by a memory controller, wherein the row activation command includes a bank address. The method also includes activating a word line in a bank of one of the memory devices based on the row activation command, wherein the bank address is used to select the memory device.
摘要:
A method for setting an address of a rank in a memory module having a number of memory chips distributed along a byte lane includes setting the first memory chip of the byte lane to have a first rank address, generating a second rank address therein from the first rank address, and driving the second rank address to a second one of the memory chips. Alternatively, the first rank address may be driven to the second memory chip, and then, a second rank address is generated in that second memory chip. Further, the second memory chip is set to have the second rank address in response to the driving the second/first rank address. A power-up sequence after voltage supply, or command signals sent via a serial management bus or the command address bus can be used to initiate the setting of ranks. The rank addresses are re-driven to adjacent memory chips by DQ-lines along a byte lane.
