Patent ID: 8825939

Claim:
A system, comprising: a point-to-point ring topology comprising a plurality of semiconductor memory devices; and a controller for communicating with the devices, said controller comprising: a plurality of outputs for providing to a first one of the devices a command latch enable signal, an address latch enable signal and an information signal; a plurality of outputs for independently providing a respective select signal to each of the devices; control logic configured to select a particular one of the devices and to issue specific information to the particular one of the devices by controlling the command latch enable signal, the address latch enable signal and the information signal provided to the first device, wherein when the particular one of the devices is not the first one of the devices, the command latch enable signal, the address latch enable signal and the information signal are daisy-chained from the first one of the devices to the particular one of the devices via the point-to-point ring topology; and wherein the control logic is further configured to convey via the select signal independently provided to the particular one of the devices that the particular one of the devices has been selected while conveying via the select signals independently provided to the other devices that the other devices have not been selected.
