The new one-time password is then saved as an “old” password for subsequent combination with the secret when coming out of subsequent suspend states.

| 20080270811 | Fast Suspend-Resume of Computer Motherboard Using Phase-Change Memory - A personal computer motherboard has a main memory of phase-change-memory (PCM) chips in PCM memory modules. An operating system (OS) image is stored in the PCM memory modules and is retained during suspend since the PCM chips are non-volatile. The microprocessor can directly read the OS image retained in the PCM memory modules without copying an OS image from a hard disk to the main memory upon resume. Therefore a boot loader program in the boot ROM does not have to be fetched to the microprocessor for suspend/resume. The video memory can also be PCM, allowing the frame buffer to be retained during suspend/resume, yet be directly addressable by the microprocessor. The display is quickly activated since the frame buffer does not have to be re-constructed after suspend/resume. PCM cells use amorphous and crystalline states of a variable resistor to store data. | 10-30-2008 |
