This paper proposes a compact single-bit line SRAM memory cell, which we call an asymmetric memory cell (AMC), using a complementary thin-film transistor (C-TFT). A C-TFT is composed of a top-gate n-channel TFT and a bottom-gate p-channel TFT. The pr

The variation of the threshold voltage shift (V/sub th/ shift) caused by negative-bias temperature stress (-BT stress) in poly-crystalline silicon thin-film transistors (poly-Si TFTs) was investigated. Based on the chemical reaction caused by -BT str

We propose a vertical /spl Phi/-shape transistor (V/spl Phi/T) cell for 1 Gbit DRAM and beyond. The V/spl Phi/T is a vertical MOSFET whose gate surrounds its channel region like a Greek-alphabetic letter /spl Phi/, fabricated through the penetration

A new architecture for serial access memory is described that enables a static random access memory (SRAM) to operate in a serial access mode. The design target is to access all memory address serially from any starting address with an access time of

A compact SRAM memory cell structure using a set of C-TFTs (complementary thin-film transistors) is discussed. A C-TFT is composed of a top-gate N-channel TFT and a bottom-gate P-channel TFT. The proposed cell's size was reduced to 80% of that of a c

We propose a novel single-bit-line SRAM cell called a Complementary-Switch (C-Switch) cell. This cell features a C-Switch which combines an n-channel bulk transistor and a p-channel TFT in parallel. Through the use of a single-bit-line architecture w
