Abstract
A memory structure including a first select transistor, a first floating gate transistor, a second select transistor, a second floating gate transistor, and a seventh doped region is provided. The first select transistor includes a select gate, a first doped region, and a second doped region. The first floating gate transistor includes a floating gate, the second doped region, and a third doped region. The second select transistor includes the select gate, a fourth doped region, and a fifth doped region. The second floating gate transistor includes the floating gate, the fifth doped region, and a sixth doped region. A gate width of the floating gate in the second floating gate transistor is greater than a gate width of the floating gate in the first floating gate transistor. The floating gate covers at least a portion of the seventh doped region.
