Intel 25nm is MLC, has been for a while now.
All they announced today is that they are sampling TLC chips produced on the same process node and are working with integrators to create products based on them.
Intel is releasing a 25 nm 3BPC flash - this is designed for minimum price and maximum capacity for bottom-end storage. E.g. things like USB keys, memory cards for MP3 players, PDAs, etc.
This bottom tier storage market is driven by price - and very low performance (5 MB/s) and very low endurance (100-1000 cycles) don't matter for these types of application.
For higher-end storage, Intel also has a conventional 2BPC flash which is intended for consumer-level SSDs and for high-end memory cards. The performance is better, cycle life time is higher and the data integrity is higher.
For top-end storage, they also have 25 nm enterprise-grade 2BPC flash, with enhanced durability (estimated 30k cycles), slightly better bit-error rate and improved performance. This is intended for enterprise level SSDs.
P.S. I really wish people wouldn't use abbreviations like 3LC or TLC. I know they are used in industry - but they are gibberish. Conventional 2BPC MLC has 3 levels and can accurately be described as 3LC - so you can see the immense confusion. It's worse because 3BPC has 7 level cells, and there's no way to sensibly get the abbreviation 3LC (or TLC) from 3BPC. Maybe 3MLC may be a better abbreviation.
