ISSI 512Mbx8 & 256Mbx16 DDR4 SDRAM
ISSI 512Mbx8 and 256Mbx16 DDR4 SDRAM are high-speed dynamic random-access memory devices internally organized with an eight-bank setup. Double Data Rate 4 Synchronous Dynamic Random Access Memory banks are organized into two groups each with four DRAM banks. DDR4 SDRAM uses a 8n prefetch architecture to achieve high-speed operation. ISSI 4GB DDR4 SDRAM devices deliver high-speed data transfer rates up to 2666Mbps making them ideal for telecom and networking, automotive, and industrial embedded computing.
