Abstract
Systems, methods, and/or devices that facilitate accessing data from memory are presented. An adaptive detection component can be employed to reduce or minimize detection error and distinguish information stored in memory cells during read operations. A decoder component can include the adaptive detection component, which can employ an adaptive Linde-Buzo-Gray (LBG) algorithm. The decoder component can receive information associated with a current level from a memory location during a read operation, and can analyze and process such information. The adaptive detection component can receive the processed information and, along with other information, can process such information using the iterative LBG algorithm until reconstruction levels and corresponding threshold levels are determined. Such reconstruction levels and/or threshold levels can be compared to the value associated with the information read from the memory location to determine the data value of the data in the memory location.
