HYE18M1G320BF-7.5

Product Summary

The HYE18M1G320BF-7.5 is a high-speed CMOS, dynamic random-access memory containing 1,073,741,824 bits. The HYE18M1G320BF-7.5 is internally configured as a quad-bank DRAM. The HYE18M1G320BF-7.5 uses a double-data-rate architecture to achieve high-speed operation. The double-data-rate architecture is essentially a 2n pre fetch architecture, with an interface designed to transfer two data words per clock cycle at the I/O balls. A single READ or WRITE access for the DDR Mobile-RAM consists of a single 2n-bit wide, one clock cycle data transfer at the internal DRAM core and two corresponding n-bit wide, one-half clock cycle data transfers at the I/O balls.
