Working Principle of AS4C4M16SA-6TAN

The AS4C4M16SA-6TAN has a 6T cell configuration that utilizes a small 6 transistor type cell for high-speed operation. The device is composed of two arrays of memory cells and a clock-free SRAM control logic to control the operation of the cells. The data stored in the memory cells is read or written by the read and write logic. The read logic is used to read the data from the memory cells. It first checks that valid data is available in the memory cells before it transfers data to the output. The write logic is used to write data to the memory cells. It checks if valid data is available before it writes data to the memory cells.

The device utilizes a patented burst counter architecture to control the access and burst size of the data. This burst counter architecture enables the device to read or write data in four successive clock cycles, allowing the memory access to operate at high speeds. Additionally, the device has a power-down feature that reduces the power consumption and complexity of the device. When the device is not in use, it can be put into stand-by mode to reduce the power consumption.
