Zugriffstransistoren
Zugriffstransistoren, often translated as access transistors, are a fundamental component in semiconductor memory devices, particularly in dynamic random-access memory (DRAM) and static random-access memory (SRAM). Their primary function is to control the flow of electrical charge to and from the memory cell itself. In DRAM, the access transistor acts as a switch, connecting or disconnecting the storage capacitor from the bit line. When activated by a control signal from the word line, the transistor allows data, represented by a charge on the capacitor, to be read or written.
In SRAM, access transistors, typically MOSFETs (metal-oxide-semiconductor field-effect transistors), form the core of each memory cell,
