Micron 256GB Asynchronous/Synchronous NAND Flash Memory

Micron 256GB Asynchronous/Synchronous NAND Flash Memory devices use a highly multiplexed 8-bit bus (DQx) to transfer commands, address, and data. The memory device offers a Single-Level Cell (SLC) architecture for superior endurance and data integrity. These devices come with five control signals used to implement the asynchronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional signals control hardware write protection (WP#) and monitor device status (R/B#). The NAND Flash device additionally includes a synchronous data interface for high-performance I/O operations. These NAND flash operate at 2.7V to 3.6V supply voltage and 1.8V I/O voltage, making it ideal for low-power designs. The 256GB NAND Flash memory comes in a 100-ball LBGA package (12mm x 18mm). These memory devices support an extended temperature range of -40°C to 85°C for industrial-grade reliability. The 256GB Asynchronous/Synchronous devices are ideal for automotive systems, industrial controllers, networking equipment, and high-reliability embedded storage solutions.
