A flexible disposable bioreactor having three, stagger-baffled compartments wherein the middle compartment houses a sparging rod is described to provide the highest degree of sparging and mixing to produce biological products. The memory device includes a memory array of multi-level cell memory cells configured to store a first portion of logic states and a second portion of logic states. The leakage in the transmission signal is relocated based at least in part on the frequency change. The attachment assembly is disposed in another of the grooves formed in the chassis for engaging at least one of the adjacent support beams.
