Abstract

Methods, systems, and apparatuses for updating pointers in memory are described. A device can include pointer logic and a memory that stores a memory pointer. The pointer logic can increment or decrement the memory pointer according to Gray code. The device can increment or decrement the memory pointer in response to a pointer change command and can be configured to first verify a password associated with the command. The device can send an acknowledgement that the command has been received and/or executed. Multiple increments or decrements of the memory pointer can occur in response to a pointer change command configured as a single multiple-increment-or-decrement command or as multiple single-increment-or-decrement change commands. The device can determine an updated value for each of a first memory pointer portion and a second memory pointer portion of the memory pointer.
