Abstract: A memory subsystem is enabled with a write pattern command. The write pattern command can have a different command encoding from other write commands. The write pattern command triggers a dynamic random access memory (DRAM) device to write a data pattern that is internally generated, instead of a bit pattern on the data signal lines of the data bus. The internally generated data pattern can be read from a register, such as a mode register. In response to a write pattern command, the DRAM device provides the write pattern data from the register to the memory array to write. Thus, the memory controller does not need to send the data to the memory device.

Abstract: Examples include techniques to change a mode of operation for a memory device. Examples include using information stored at a memory array of the memory device to program mode registers at the memory device to change the mode of operation to a first mode of operation that corresponds to a frequency set point associated with dynamic voltage and frequency scaling for a processor coupled with the memory device.

Abstract: A multi-die memory device having fixed bandwidth interfaces can selectively connect portions of the interfaces of the multiple memory dies as a memory channel for the multi-die device. The selective application of the interface bits of the memory dies enables the application of ECC (error checking and correction) in memory devices that otherwise have insufficient connectors to exchange ECC information. The device includes circuitry to selectively apply CAS (column address select) signals to the memory dies to selectively connect the connectors of the memory dies. CAS selection can provide various configurations in which selected bits of a first memory die interface are combined with selected bit or bits of a second memory die interface to provide the device interface. The memory dies can operate in byte mode to apply only half of their data I/O (input/output) interface, with CAS doubled up to provide access to the memory arrays.
