HY27UF(08/16)2G2B Series
2Gbit (256Mx8bit) NAND Flash
FEATURES SUMMARY
HIGH DENSITY NAND FLASH MEMORIES
- Cost effective solutions for mass storage applications
MULTIPLANE ARCHITECTURE
- Array is split into two independent planes. Parallel
Operations on both planes are available, halving
Program and erase time.
NAND INTERFACE
- x8/x16 bus width.
- Address/ Data Multiplexing
- Pinout compatiblity for all densities
SUPPLY VOLTAGE
- 3.3V device : Vcc = 2.7 V ~3.6 V
MEMORY CELL ARRAY
- x8 : (2K + 64) bytes x 64 pages x 2048 blocks
- x16 : (1K + 32) words x 64 pages x 2048 blocks
PAGE SIZE
- (2K + 64 spare) Bytes

- Multi-page program time (2 pages) : 200us (typ.)
COPY BACK PROGRAM
- Automatic block download without latency time
FAST BLOCK ERASE
- Block erase time: 1.5ms (typ.)
- Multi-block erase time (2 blocks) : 1.5ms (typ.)
CACHE READ
