Abstract: A method for replacing data on a volatile memory cache is provided. The volatile memory cache includes one or more memory banks and each of the memory banks includes a plurality of memory lines. The method includes: identifying a replacement ID for at least one of the memory lines to be replaced; identifying a refresh bank ID for one of the memory banks to be refreshed; determining whether or not a conflict exists between the replacement ID and the refresh bank ID; and selecting a new replacement ID if the conflict exists.

Abstract: A method includes: providing a DDR interface between a host memory controller and a memory module; and providing a message interface between the host memory controller and the memory module. The memory module includes a non-volatile memory and a DRAM configured as a DRAM cache of the non-volatile memory. Data stored in the non-volatile memory of the memory module is asynchronously accessible by a non-volatile memory controller of the memory module, and data stored in the DRAM cache is directly and synchronously accessible by the host memory controller.

Abstract: A method for addressing memory device data arranged in rows and columns indexed by a first number of row address bits and a second number of column address bits, and addressed by a row command specifying a third number of row address bits followed by a column command specifying a fourth number of column address bits, the first number being greater than the third number or the second number being greater than the fourth number, includes: splitting the first number of row address bits into first and second subsets, and specifying the first subset in the row command and the second subset in a next address command when the first number is greater than the third number; otherwise splitting the second number of column address bits into third and fourth subsets, and specifying the fourth subset in the column command and the third subset in a previous address command.

Abstract: A secure memory (145) is disclosed. The memory (145) may include data storage (310, 315, 320, 325, 330, 335, 340, 345) for data, along with a data read logic (405) and a data write logic (410) to read and write data from the data storage (310, 315, 320, 325, 330, 335, 340, 345). A password storage (355) may store a stored password (510). A receiver may receive a received password (505) from a memory controller (205). A comparator may compare the received password (505) with the stored password (510). An erase logic (435) may erase data in the data storage (310, 315, 320, 325, 330, 335, 340, 345) if the received password (505) does not match the stored password (510). Finally, a block logic (425) may block access to the memory (145) from the memory controller (205) until after the comparator (430) completes its operation.
