Abstract: A memory system architecture has serially connected memory devices. The memory system is scalable to include any number of memory devices without any performance degradation or complex redesign. Each memory device has a serial input/output interface for communicating between other memory devices and a memory controller. The memory controller issues commands in at least one bitstream, where the bitstream follows a modular command protocol. The command includes an operation code with optional address information and a device address, so that only the addressed memory device acts upon the command. Separate data output strobe and command input strobe signals are provided in parallel with each output data stream and input command data stream, respectively, for identifying the type of data and the length of the data. The modular command protocol is used for executing concurrent operations in each memory device to further improve performance.

Abstract: A channel has a first and a second end. The first end of the channel is coupled to a transmitter. The channel is capable of transmitting symbols selected from a symbol set from the first end to the second end. The channel exhibits incomplete error introduction properties. A code comprises a set of code words. The elements of the set of code words are one or more code symbols long. The code symbols are members of the symbol set. The minimum modified Hamming separation between the elements of the set of code words in light of the error introduction properties of the channel is greater than the minimum Hamming distance between the elements of the set of code words. A memory device, a method of using the channel, and a method of generating the code are also described.

Abstract: In a ring-of-clusters network topology, groups of slave devices are accessed in parallel, such that the latency around the ring is proportional to the number of clusters and not proportional to the number of integrated circuits. The devices of a cluster share input and output ring segments such that packets arriving on the input segment are received and interpreted by all the devices in a cluster. In other embodiments, none, some or all but one slaves per cluster are asleep or otherwise disabled so that they do not input and interpret incoming packets. Regardless, in all embodiments, the slaves of a cluster cooperate, potentially under the controller's direction, to ensure that at most one of them is actively driving the output segment at any given time. The devices may be addressed through a device ID, a cluster ID, or a combination thereof. Embodiments of the invention are suited to exploit multi-chip module implementations and forms of vertical circuit stacking.
