Methods, devices, and systems relating to memory cells having a floating body
Abstract:
Methods, devices, and systems are disclosed relating to a memory cell having a floating body. A memory cell includes a transistor comprising a drain and a source each formed in silicon and a gate positioned between the drain and the source. The memory cell may further include a bias gate recessed into the silicon and positioned between an isolation region and the transistor. In addition, the bias gate may be configured to be operably coupled to a bias voltage. The memory cell may also include a floating body within the silicon. The floating body may include a first portion adjacent the source and the drain and vertically offset from the bias gate and a second portion coupled to the first portion. Moreover, the bias gate may be formed adjacent to the second portion.
