The K8S2815E featuring single 1.8V power supply is a 128Mbit Synchro-
nous Burst Multi Bank Flash Memory organized as 8Mx16. The memory
architecture of the device is designed to divide its memory arrays into 263
blocks with independent hardware protection. This block architecture pro-
vides highly flexible erase and program capability. The K8S2815E 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 K8S2815E provides an 14.5ns burst
access time and an 70ns initial access time at 54MHz. At 66MHz, the
K8S2815E provides an 11ns burst access time and 70ns initial access time.
At 83MHz, the K8S2815E provides an 9ns burst access time and 70ns ini-
tial access time. At 108MHz, the K8S2815E provides an 7ns burst access
time and 70ns initial access time. The device performs a program operation
in units of 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 0.7sec. The device requires 15mA as program/erase current
in the extended temperature ranges.
The K8S2815E NOR Flash Memory is created by using Samsung's
advanced CMOS process technology.
