    LPDDR2 Innovations

    Rambus is not dead yet. They are not one trick pony.
    Numerous Rambus innovations, including many that have already been proven in compute and graphics applications, address these challenges for mobile memory systems. Specifically, patented Rambus innovations in LPDDR2 address both performance efficiency and power management and include:

    Efficiency Features
    Double Bus Rate Control – Doubles the per-pin signaling rate for address/control and/or data to improve bandwidth efficiency and performance.
    Strobed Write – Improves timing and efficiency of write operations using strobe timing signals.
    External and Self Refresh Continuity - Manages refresh addressing with transitions into and out of low power Self Refresh modes in order to improve channel and memory efficiency, as well as reduce controller complexity.
    Strobed Write Burst Terminate - Allows a memory controller to write data bursts of arbitrary lengths, increasing bus efficiency.
    Variable Burst Length - Improves data transfer efficiency by allowing varying amounts of data to be sent per a memory read or write request.
    Core Prefetch - Improves interface bandwidth while allowing the core to operate at a lower frequency.
    Programmable Read Latency - Allows a memory component to operate at higher frequencies by more efficiently scheduling internal memory timings.
    Power Management Features
    I/O Power Mode Management – Coordinates the control of I/O and clocking circuits to save power for low power modes, such as Deep Power-Down.
    External and Self Refresh Continuity – Manages refresh addressing with transitions into and out of low power Self Refresh modes.
    Temperature Compensated Self-Refresh (Optional) – Enables lower memory power during self-refresh by compensating the refresh rate based on temperature.
