The hash of the key includes information to identify an index entry that comprises information that maps to the location of the data item stored on the log-based storage structure.

Abstract: Systems and methods for forming a custom fitted shoe insole. The method includes placing a shoe insole template plate proximate a heating element that heats the shoe insole template plate to a temperature sufficient to make it deformable. The method further includes placing the sufficiently heated shoe insole template plate onto a foam structure, placing a foot of a user on the heated shoe insole template plate, and applying foot pressure to the heated shoe insole template plate, causing it to deform to match a topology of the sole of the user's foot. The shoe insole template plate is then removed from the foam structure, cooled and hardened, and inserted into a shoe as the custom fitted shoe insole.

The memory cell(s) store data, which may be written to, read from and held in the hardware memory. The peripheral circuitry reads and writes data to the memory cell(s) and may perform other functions necessary for facilitating the data read, write and hold. The randomization circuitry randomizes operations performed by the peripheral circuitry to reduce a correlation between the data and the current consumed by the hardware memory.
