Working Principle

AS7C32098A-12TCNTR SRAM is a two-transistor static memory cell. The memory cells are connected to two power supply pins Vcc and Vss, two word lines WL0 and WL1, and two bit lines BL0 and BL1, which are the data input and output lines.(7)

The two power supply pins Vcc and Vss provide the necessary power for the circuit. The two word lines WL0 and WL1 are used to select a pair of memory cells to be read or written. The two bit lines BL0 and BL1 are used to transmit the data of the memory cells.

Write operation: When a desired memory cell is selected by WL0 and WL1, write data will be input through BL0. The write data will apply a certain voltage between BL0 and BL1, which will cause the data to be stored in the memory cell.(7)

Reading Operation: When a desired memory cell is selected by WL0 and WL1, the data stored in the memory cell will be applied between BL0 and BL1. BL0 and BL1 will read out the data with the corresponding voltage and present it at the output terminal.(7)

Conclusion

In conclusion, AS7C32098A-12TCNTR is a high-speed static RAM (SRAM) which belongs to the Memory category. It is suitable for applications such as mobile phones, digital cameras, audio-visual equipment, digital TVs, PC peripherals, wireless, home entertainment, etc. It has the advantages of low operating voltage, high speed and high performance, compact package structure and high reliability. Its working principle is that when a desired memory cell is selected by WL0 and WL1, write data will be input through BL0 and stored in the memory cell, or the data stored in the memory cell will be applied between BL0 and BL1 and read out at the output terminal.
