Rookie questions on SPI NAND flash

[inklen]

Hello,

I've never looked at SPI NAND Flash IC's but I'd like to use one now. I've read some datasheets but I have some questions if you don't mind. For example, this Micron Nand Flash memory.
If we take 2Gb one, they say:

Page size:
x8: 2,112 bytes (2,048 + 64 bytes)
x16: 1,056 words (1,024 + 32 words)
• Block size: 64 pages (128K + 4K bytes)
• Device size: 2Gb: 2,048 blocks; 4Gb: 4,096 blocks;
8Gb: 8,192 blocks

Do I understand this right that 2Gb is 256 Mb (megabyte)? 2048 bytes * 64 pages * 2048 blocks = 268435456 bytes = 256 Mb.

Another question - I don't understand their clock requirements. Will it work at 4MHz? 1 Mhz?

I appreciate some answers.

Hi,

It´s no SPI device.
What clock are you talking about?

Klaus

btw:
Yes. 2 GBit, 256 MByte

NAND flash has basically static interface. No clock involved.

The idea is to use SPI NAND flash with MCU. MCU provides a clock (1 - 4 MHz).

Found this one - Micron MT29F1G01ABBFDWB 1Gb. It is SPI. But I wonder if it works with 1 or 4 MHz clock.

Hi,

You refer to a seller's site instead of a datasheet.

That's because you need to register on Micron site to get their datasheets. Here's their datasheet.

Hi,

Then register.
Any one needs to read the datasheet. Best if you do.

I did from the beginning. The datasheet has max frequency but not the minimum.

 

[KlausST]

Hi,

Lucky you, if there is no minimum. Nothing special for an SPI device.
Accept it and be happy.

Thank you, Klaus. Good to know for sure.
