Fundamentals of MirrorBit Technology
The MirrorBit cell doubles the density of a Flash memory array by storing two physically distinct quantities of charge on opposite sides of a memory cell – a feat made possible by the non-conducting nature of the storage medium. In this two-bit cell, each bit serves as a binary unit of data (either 1 or 0) that is mapped directly to the memory array.
Reading or writing a bit on one side of a memory cell occurs independently of the data that is stored on the opposite side of the cell. Because of its symmetrical memory cell and nonconductive storage element, MirrorBit technology has been engineered to take advantage of a simple, efficient memory array. This array design significantly simplifies a device’s topography and manufacturing process. The end result is a technology that requires 40 percent fewer critical manufacturing steps than floating-gate NOR and consequently provides industry leading price-performance for Flash memory.
