Abstract

A memory array, a memory structure and an operation method of a memory array are provided. The memory array includes memory cells, floating gate transistors, bit lines and word lines. The memory cells each comprise a capacitor and an electrically programmable non-volatile memory (NVM) serially connected to the capacitor, and further comprise a write transistor with a first source/drain terminal coupled to a common node of the capacitor and the electrically programmable NVM. The floating gate transistors respectively have a gate terminal electrically floated and coupled to the capacitors of a column of the memory cells. The bit lines respectively coupled to the electrically programmable NVMs of a row of the memory cells. The word lines respectively coupled to gate terminals of the write transistors in a row of the memory cells.
