FLASH MEMORY
GENERAL DESCRIPTION
The K8D3216U featuring single 3.0V power supply, is a 32Mbit
NOR-type Flash Memory organized as 4Mx8 or 2M x16. The
memory architecture of the device is designed to divide its
memory arrays into 71 blocks to be protected by the block
group. This block architecture provides highly flexible erase and
program capability. The K8D3216U NOR Flash consists of two
banks. This device is capable of reading data from one bank
while programming or erasing in the other bank. Access times
of 70ns, 80ns and 90ns are available for the device. The
device′s fast access times allow high speed microprocessors to
operate without wait states. The device performs a program
operation in units of 8 bits (Byte) or 16 bits (Word) and erases 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 standard
and industrial temperature ranges.
The K8D3216U NOR Flash Memory is created by using Sam-
sung's advanced CMOS process technology. This device is
available in 48 pin TSOP1 and 48 ball TBGA, FBGA packages.
The device is compatible with EPROM applications to require
high-density and cost-effective nonvolatile read/write storage
solutions.
