A device for use in measuring andor analyzing at least one parameter of an external portion of a body comprises at least one surface configured to be placed in the vicinity of said external portion. These techniques are particularly applicable to memory devices have a 3D structure, such as of BiCS type, where the slow programming can arise from defects of the spacing between the memory holes, in which the NAND strings are formed, and the local interconnects, such as for connecting common source lines and which run in a vertical direction between groups of NAND strings. A row selector circuit selects and drives one of the rows in response to the address. According to another embodiment the housing in the proximity of the fixtures of the motor is formed such that the housing acts as spring element itself. Some mechanisms for moving the reference elements on the user interface are drag and drop andor cut and paste procedures.
