| 20080215918 | METHOD FOR MONITORING SERVER SUB-SYSTEM HEALTH - A server self health monitor (SHM) system monitors the health of the server it resides on. The health of a server is determined by the health of all of a server's sub-systems and deployed applications. The SHM may make health check inquiries to server sub-systems periodically or based on external trigger events. The sub-systems perform self health checks on themselves and provide sub-system health information to requesting entities such as the SHM. Sub-systems self health updates may be based on internal events such as counters or changes in status or based on external entity requests. Corrective action may be performed upon sub-systems by the SHM depending on their health status or the health status of the server. Corrective action may also be performed by a sub-system upon itself. | 09-04-2008 |

| 20120239976 | APPARATUS AND METHOD FOR DETERMINING A READ LEVEL OF A FLASH MEMORY AFTER AN INACTIVE PERIOD OF TIME - Disclosed is an apparatus and method for determining a dwell time in a non-volatile memory circuit after a shutdown of the memory circuit. A voltage shift is calculated by comparing a first read level voltage required to read a test block stored before the shutdown and a second read level voltage required to read a second test block stored after the shutdown. A shutdown time is determined from a look up table indexed by the voltage shift and a number of program/erase cycles. The dwell time is calculated as a function of the drive temperature, a clock, and a block time stamp. Once the dwell time is calculated, a controller calculates a new read level voltage based, in part, on the dwell time and provides one or more programming commands representative of the new read level voltage to the memory circuit to read the memory circuit. | 09-20-2012 |
