ISSI DDR4 DRAM

ISSI DDR4 DRAM is a high-speed dynamic random-access memory device 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 an 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.
