A memory module and a memory module system are provided. The memory module system includes a plurality of memory modules each module comprising a plurality of memory blocks and a plurality of corresponding routers each storing a channel identification (ID) and a module ID corresponding to one or more memory blocks; and a controller configured to access the memory modules. During initialization, the controller reads and stores the channel ID and the module ID from each of the routers. The controller outputs a channel ID and a module ID that correspond to one or more memory blocks to be accessed.

Memory module and memory module system

A controller and a memory subsystem including a plurality of memory banks each having a plurality of memory devices, in which the controller includes a memory device configured to store an identification (ID) of each of the plurality of memory banks; and a control logic configured to read an ID of a memory bank to be accessed among the plurality of memory banks from the memory device, then output the ID, and then output a command. Each of the plurality of memory devices includes an input port, a register configured to store an ID of each memory device, and a determination circuit configured to receive and compare an ID input via the input port with the ID stored in the register and to generate a control signal according to a result of the comparison. The input port is enabled or disabled in response to the control signal.

Memory subsystem capable of accessing a plurality of memory bank identifications and method thereof

A communication device and method is provided, comprising: a signal modulator/demodulator having a digital signal processor for effecting radio communications; and an application processor (AP) having a central processing unit and a master controller for controlling via a common bus a plurality of peripherals including an interface with the signal modulator/demodulator, wherein a memory shared by the modem and the AP is controlled via the interface. The plurality of peripherals include at least one of an image capture module, a display, and a flash memory. The master controller controls the plurality of peripherals by issuing a packetized command commonly receivable by the plurality of peripherals over the common bus, the packetized command includes a module device select signal used for selecting one of the peripherals.
