rev 0.2 / mar. 2005 3 preliminary hy27ug(08/16)2g2m series hy27sg(08/16)2g2m series 2gbit (256mx8bit / 128m x16bit) nand flash 1. summary description the hynix hy27(u/s)g(08/16)2g2m series is a 256mx8bit with spare 8mx8 bit capa city. the device is offered in 1.8v vcc power supply and 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 indepe ndently so it is possible to preserve valid data while old data is erased. the device contains 2048 blocks, composed by 64 pages cons isting in two nand structures of 32 series connected flash cells. a program operation allows to write the 2112-byte page in typical 300us and an erase operation can be performed in typical 2ms on a 128k-byte(x8 device) block. data in the page mode can be read out at 50ns cycle time per word. the i/o pins serve as the ports for address and data input/output as well as command input. this interface allows a reduced pin count and easy migration towards dif- ferent densities, without any rearrangement of footprint. commands, data and addresses are synchronously in troduced using ce#, we#, ale and cle input pin. the on-chip program/erase controller automates all progra m and erase functions including pulse repetition, where required, and internal verifica tion and margining of data. the modifying can be locked using the wp# input pin or using the extended lock block feature described later. the output pin rb# (open drain buffer) signals the status of the device during each operat ion. in a system with mul- tiple memories the rb# pins can be connected al l together to provide a global status signal. even the write-intensive systems can take advantage of th e hy27(u/s)g(08/16)2g2m extended reliability of 100k pro- gram/erase cycles by providing ecc (error correc ting code) with real time mapping-out algorithm. optionally the chip could be offered with the ce# don?t care function. this option allows the direct download of the code from the nand flash memory device by a microcontrol ler, since the ce# transitions do not stop the read opera- tion. the copy back function allows the opti mization of defective blocks management: when a page program operation fails the data can be directly programmed in another page inside the same array section withou t the time consuming serial data insertion phase. the cache program feature allows the data insertion in the ca che 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 implemente d. this feature allows to dramatically improve the read throughput when con- secutive pages have to be streamed out. this device includes also extra features like otp/unique id area, automatic read at power up, read id2 extension. the hynix hy27(u/s)g(08/16)2g2m seri es is available in 48 - tsop1 12 x 20 mm , 48 - wsop1 12 x 17 mm, fbga 9.5 x 12 mm. 1.1 product list part number orization vcc range package hy27sg082g2m x8 1.70 - 1.95 volt 63fbga / 48tsop1 / 48wsop1 HY27SG162G2M x16 hy27ug082g2m x8 2.7v - 3.6 volt hy27ug162g2m x16
