256M Bit (16M x16) Synch Burst , Multi Bank SLC NOR Flash Memory

GENERAL DESCRIPTION

The K8A(56/57)15E featuring single 1.8V power supply is a 256Mbit Burst Multi Bank Flash Memory organized as 16Mx16. The memory architecture of the device is designed to divide its memory arrays into 256 blocks(Uniform block part)/259 blocks(Boot block part) with independent hardware protection. This block architecture provides highly flexible erase and program capability. The K8A(56/57)15E NOR Flash consists of sixteen banks. This device is capable of reading data from one bank while programming or erasing in the other bank.
Regarding read access time, the K8A5615E provides an 11ns burst access time and an 95ns initial access time at 66MHz. At 83MHz, the K8A5615E provides an 9ns burst access time and an 95ns initial access time. At 108MHz, the K8A5715E provides an 7ns burst access time and an 95ns initial access time. At 133MHz, the K8A5715E provides an 6ns burst access time and an 95ns initial access time.
