The present invention determines or identifies programming variations for different groups within an array or memory device that properly program memory cells within the respective groups. Then, during programming operations for a given memory cell, programming voltages are applied according to the determined or identified programming variations for the group to which the given memory cell belongs. These adjusted programming variations facilitate successful programming of the particular memory cell.

An aspect of the present invention relates to a magnetic recording medium comprising a nonmagnetic layer containing a nonmagnetic powder and a binder and a magnetic layer containing a ferromagnetic powder and a binder in this order on a nonmagnetic support, whereinthe magnetic layer comprises a nonmagnetic powder of which coefficient of variation CV of a particle size distribution as denoted by the following formula (1):CV(%)=σ / φ×100  (1)is less than 20 percent, andthe magnetic layer has a thickness being equal to or less than 0.1 μm and falling within a range of 1.1≦φ / t≦8.0, wherein σ denotes a standard deviation of a particle diameter, φ denotes an average particle diameter of the nonmagnetic powder comprised in the magnetic layer being expressed in μm, and t denotes a thickness of the magnetic layer being expressed in μm.

Provided are an optimized tool apparatus and methods for dry transfer printing of semiconductor elements with high yield and good placement accuracy. The tool apparatus comprises a vacuum coupled fast peel apparatus that provides high pickup yield of the semiconductor elements. In an aspect, this vacuum coupled apparatus provides high pickup rates during pickup of the semiconductor elements from a donor / source wafer. Provided is a tool apparatus for dry transfer printing with a reinforced composite stamp having a thin glass-backing. The tool apparatus also comprises a pressure regulated micro-chamber which provides precise control of a composite stamp lamination and de-lamination. In an aspect, the micro-chamber has an internal cavity volume that is variably controlled, thereby providing precise control of the force on the stamp, and corresponding separation velocity, and improved semiconductor element pick-up and / or placement.

The present invention relates to hyperbranched copolymers and compositions in which they are incorporated, e.g., colorant compositions, tint bases, and coatings such as latex paint, and methods for making such copolymers and compositions.
