Abstract: Systems and methods are disclosed for managing the peak power consumption of a system, such as a non-volatile memory system (e.g., flash memory system). The system can include multiple subsystems and a controller for controlling the subsystems. Each subsystem may have a current profile that is peaky. Thus, the controller may control the peak power of the system by, for example, limiting the number of subsystems that can perform power-intensive operations at the same time or by aiding a subsystem in determining the peak power that the subsystem may consume at any given time.

Abstract: This can relate to handling a non-volatile memory (“NVM”) operating at a substantially full memory. The non-volatile memory can report its physical capacity to an NVM driver. The NVM driver can scale-up the physical capacity a particular number of times to generate a “scaled physical capacity,” which is then reported to the file system. Because the scaled physical capacity is greater than the NVM's actual physical capacity, the file system allocates a logical space to the NVM that is substantially greater than the NVM's capacity. This can cause less crowding of the logical block addresses within the logical space, thus making it easier for the file system to operate and improving system performance. A commitment budget can also be reported to the file system that corresponds to the NVM's physical capacity, and which can define the amount of data the file system can commit for storage in the NVM.

Abstract: Systems and methods are provided for testing a non-volatile memory, such as a flash memory. The non-volatile memory may be virtually partitioned into a test region and a general purpose region. A test application may be stored in the general purpose region, and the test application can be executed to run a test of the memory locations in the test region. The results of the test may be stored in the general purpose region. At the completion of the test, the test results may be provided from the general purpose region and displayed to a user. The virtual partitions may be removed prior to shipping the electronic device for distribution.
