EN27LN51208 Datasheet, PDF (2/46 Pages) Eon Silicon Solution Inc. – 512 Megabit (64 M x 8) SLC, 3.3 V NAND Flash Memory
2. General Description
EN27LN51208
The Eon EN27LN51208 is a 64Mx8bit with spare 2Mx8bit capacity. The device is offered in 3.3V Vcc
Power Supply. Its NAND cell provides the most cost-effective solution for the solid state mass storage
market. The memory is divided into blocks that can be erased independently so it is possible to preserve
valid data while old data is erased.
The device contains 512 blocks, composed by 64 pages consisting in two NAND structures of 32 series
connected Flash cells. A program operation allows to write the 2,112-Byte page in typical 250us and an
erase operation can be performed in typical 2ms on a 128K-Byte for X 8 device block.
Data in the page mode can be read out at 25ns cycle time per Word. The I/O pins serve as the ports for
address and command inputs as well as data input/output. The copy back function allows the
optimization of defective blocks management: when a page program operation fails the data can be
directly programmed in another page inside the same array section without the time consuming serial
data insertion phase. The cache program feature allows the data insertion in the cache register while
the data register is copied into the Flash array. This pipelined program operation improves the program
throughput when long files are written inside the memory. A cache read feature is also implemented.
This feature allows to dramatically improving the read throughput when consecutive pages have to be
streamed out. This device includes extra feature: Automatic Read at Power Up.
