⌦ Async. NAND Interface with 3.3V VCCq:
SK6226BAPQC: single channel and 8 CE/channel.
SK6226BAPMC4: single channel and 4 CE/channel.
⌦ DDR NAND interface:
1.8V or 3.3V VCCq DDR NAND, either ONFI 2.x NAND or Toggle-mode NAND.
SK6226BAPQC: single channel and 8 CE/channel with 1.8V/3.3V VCCq.
SK6226BAPMC4: single channel and 4 CE/channel with 1.8V/3.3V VCCq.
⌦ Built-in Watch-Dog Timer (WDT)
⌦ Enable Multi-Partition features:
One Read-only Partition, two Read-Write Partitions and one Hidden Partition.
Read-only Partition is designated for AutoRun feature.
UFD can have up to two LUNs because to two Read-Write Partitions.
Each Read-Write Partition can be divided into Public Zone and Private Zone further.
Private Zone can be protected by password.
Capacity of each Partition and Zone can sizeable while factory initialization or by application
program through vendor specific command.
