WebFigure 10.1: Schematic of precharge circuit for 6T SRAM. Precharge circuit for loadless 4T RAMs is shown in theschematic below. Two transistors will precharge the bitlines while the other transistor will equalize them to ensure both bit lines within a pair are at the same potential before the cell is read. WebA circuit diagram and timing chart of differential SRAM is shown in Figure 3. The bit lines indicated by true bit line (BLT) and compliment bit line (BLC) in the diagram are connected to many memory cells. The memory cells hold data by interconnecting the input and output of two inverters. WebStatic RAM (SRAM) consists of flip-flops, a bistable circuit composed of four to six transistors. Once a flip-flop stores a bit, it keeps that value until the opposite value is stored in it. SRAM gives fast access to data, but it is physically relatively large.… Read More In computer: Main memory son of man tarzan broadway
