Abstract: A wrist-worn device monitors movements of a user with a flexible circuit member. The flexible circuit member is fault tolerant. It may contain extra and/or redundant traces as well as the ability to store data on RAM if the flash memory fails or if some or all trace connections between the processor and flash memory fail. Data stored on the RAM may or may not contain less fidelity. Lower fidelity data may be used to alleviate issues arising if the RAM has less storage capacity than the flash memory.

Abstract: Systems, methods, and apparatuses for implementing selective victimization to reduce power and utilized bandwidth in a multi-level cache hierarchy. Each set of an upper-level cache includes a counter that keeps track of the number of times the set was accessed. These counters are periodically decremented by another counter that tracks the total number of accesses to the cache. If a given set counter is below a certain threshold value, clean victims are dropped from this given set instead of being sent to a lower-level cache. Also, a separate counter is used to track the total number of outstanding requests for the cache as a proxy for bus-bandwidth in order to gauge the total amount of traffic in the system. The cache will implement selective victimization whenever there is a large amount of traffic in the system.

The method further includes: if the logical unit corresponding to the received data belongs to the first area, programming the received data into a first active physical erasing unit, and if the logical unit corresponding to the received data belongs to the first area, programming the received data into a second active physical erasing unit. Accordingly, the method may improve the efficiency of a garbage collection operation.

Abstract: A system and method for efficiently limiting storage space for data with particular properties in a cache memory. A computing system includes a cache array and a corresponding cache controller. The cache array includes multiple banks, wherein a first bank is powered down. In response a write request to a second bank for data indicated to be stored in the powered down first bank, the cache controller determines a respective bypass condition for the data. If the bypass condition exceeds a threshold, then the cache controller invalidates any copy of the data stored in the second bank. If the bypass condition does not exceed the threshold, then the cache controller stores the data with a clean state in the second bank. The cache controller writes the data in a lower-level memory for both cases.
