  • Patent number: 7080222
    Abstract: A static random-access memory (SRAM) provides volatile storage of data in a cellular telephone. Connected to the volatile SRAM is a second SRAM that provides nonvolatile storage of data by backup battery means. Writing and reading of either volatile or nonvolatile data can occur. Additionally, provision is made to automatically back up data written to the volatile SRAM in the nonvolatile SRAM, as well as to streamline restoration of backed-up data from the nonvolatile SRAM to the volatile SRAM.

  • Patent number: 7046580
    Abstract: An apparatus for address selection including a first storage element and a second storage element coupled to an input bus. The first storage element stores a first address segment and the second storage element stores a second address segment upon the receipt of respective complementary clock signals. An internal address bus propagates the address segments together.

  • Patent number: 7006404
    Abstract: A memory device (200) can include memory cell arrays (202-a and 202-b) accessed according to phase shifted clock signals. Memory cell array (202-a) can be accessed at double data rates essentially synchronous with clock signal CLK. Memory cell array (202-b) can be accessed at double data rates essentially synchronous with a phase delayed clock signal DCLK. Such an arrangement can provide eight data accesses (four reads and four writes) in a single clock cycle.

  • Patent number: 6948084
    Abstract: A method and logic for providing an asynchronous interface to a synchronous memory is disclosed. One embodiment of the present invention provides for a memory having a first logical unit which is operable to generate a synchronized clock signal in response to a chip select signal to the memory. The memory comprises synchronous memory arrays. The synchronized clock signal is input to the selected synchronous memory array. This allows an access to the synchronous memory to complete within a timing budget of the asynchronous interface. Furthermore, the memory has a second logical unit which is operable, in response to the chip select signal and a second signal input to the memory, to put an input/output bus coupled to the synchronous memory into a high impedance state by the end of the memory access. The second input signal may be a read enable or a write enable signal.

  • Patent number: 6791898
    Abstract: Embodiments of the present invention provide a memory device having multiple modes of data transfer. In one embodiment, async/sync logic and a configuration register provide for asynchronous and synchronous data transfer. The async/sync logic utilizes the configuration register and various control signals to determine whether a data transfer operation should be asynchronous or synchronous. The async/sync logic also utilizes the configuration register and various control signals to determine other functionalities of the particular data transfer mode. Functionalities may include normal and page mode, page length, bust read, linear or interleaved burst, burst wrap, burst suspend, data hold length, first access latency, transition between synchronous and asynchronous mode, and the like.
