NOR FLASH MEMORY
64M Bit (4M x16) Sync Burst , Multi Bank NOR Flash Memory
GENERAL DESCRIPTION
The K8A6415E featuring single 1.8V power supply is a 64Mbit
Muxed Burst Multi Bank Flash Memory organized as 4Mbx16.
The memory architecture of the device is designed to divide its
memory arrays into 135 blocks with independent hardware pro-
tection. This block architecture provides highly flexible erase
and program capability. The K8A6415E 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 K8A6415E provides an 14.5ns
burst access time and an 90ns initial access time at 54MHz. At
66MHz, the K8A6415E provides an 11ns burst access time and
70ns initial access time. The device performs a program opera-
tion in units of Single 16 bits (word) and an erase operation in
units of a block. Single or multiple blocks can be erased. The
block erase operation is completed within typically 0.7 sec. The
device requires 15mA as program/erase current in the
extended temperature ranges.
The K8A6415E NOR Flash Memory is created by using Sam-
sung's advanced CMOS process technology.
