Principio de funcionamiento
The IS61C6416AL uses a six-transistor (6T) CMOS SRAM cell array. Address inputs are decoded by row and column decoders to select the 16-bit word. The sense amplifiers detect the small signal from the selected cells and drive the output buffers. Chip enable (CE), output enable (OE), and write enable (WE) control the tri-state I/O and read/write operations. Byte write enables (UB, LB) allow individual high-byte and low-byte writes. The 12ns access time supports zero-wait-state operation in 50MHz+ processor systems.
