摘要： A system having serially connected memory devices in a ring topology organization to realize high speed performance. The memory devices have dynamically configurable data widths such that the system can operate with up to a maximum common number of active data pads to maximize performance, or to operate with a single active data pad to minimize power consumption. Therefore the system can include a mix of memory devices having different data widths. The memory devices are dynamically configurable through the issuance of a single command propagated serially through all the memory devices from the memory controller in a broadcast operation. Robust operation of the system is ensured by implementing a data output inhibit algorithm, which prevents valid data from being provided to the memory controller when read output control signal is received out of its proper sequence.

摘要： Status indication in a system having a plurality of memory devices is disclosed. A memory device in the system includes a plurality of data pins for connection to a data bus. The memory device also includes a status pin for connection to a status line that is independent from the data bus. The memory device also includes first circuitry for generating, upon completion of a memory operation having a first duration, a strobe pulse of a second duration much shorter than the first duration. The strobe pulse provides an indication of the completion of the memory operation. The memory device also includes second circuitry for outputting the strobe pulse onto the status line via the status pin.

摘要： A configurable memory subsystem includes a memory module with a circuit board having a first and a second memory-containing device (MCD) pair mounted thereto. Each MCD pair has a first MCD in communication with a second MCD. Each MCD has an input port, an output port, and a memory each communicating with a bridge. In response to a command, the bridge transfers at least one of a portion of a data packet from the input port to the output port or to the memory, or transfers a portion of a memory packet from the memory to the output port. A loop-back device receives the command and the data packet form the first MCD pair and transmits the command and data packet to the second MCD pair.

摘要： A system comprising a plurality of memory devices coupled by a common bus to a controller has a single serially coupled enable signal per channel. Each memory device or chip comprises a serial enable input and enable output and a register for storing a device identifier, e.g., chip ID. The memory devices are serially coupled by a serial enable link, for assertion of a single enable signal to all devices. This parallel data and serial enable configuration provides reduced per-channel pin count, relative to conventional systems that require a unique enable signal for each device. In operation, commands on the common bus targeting an individual device are asserted by adding an address field comprising a device identifier to each command string, preferably in an initial identification cycle of the command. Methods are also disclosed for initializing the system, comprising assigning device identifiers and obtaining a device count, prior to normal operation.

摘要： A memory system has a controller. A plurality of memory devices are serially interconnected with the controller via an n-bit data interface. The memory system is configurable in a first mode to communicate each read and write operation between the controller and the memory devices using all n bits of the data interface. The memory system is configurable in a second mode to concurrently: communicate data associated with a first operation between the controller and a first target memory device using only m bits of the data interface, where m is less than n; and communicate data associated with a second operation between the controller and a second target memory device using the remaining n-m bits of the data interface. A memory device, a memory controller, and a method are also described.
