In one embodiment of the present invention, a method for connecting a plurality of bit lines to sense circuitry includes providing a plurality of bit lines extending from a memory array in a first metal layer. Two side blocks are longitudinally located on two sides of the window. An opening is formed at one end of the barrel. The array controller updates a block of data contained in any one of the data storage units and the check storage units using only six IO operations. A controller communicates with the temperature sensor and the heating element and activates the heating element based on the temperature satisfying a threshold. A lighting module comprises: one or more LED packages mounted on a circuit board; and an injection overmolding sealing the circuit board, the injection overmolding not having openings corresponding to piece holding pins, the injection overmolding not covering at least a light emitting portion of the one or more LED packages.
