Message: Re: Flash Memory Fragmentation – Myths and Facts (based on the FAT system)


Kinda an oximoron sayig, no moving parts' then saying it changes, or can be changed,,, lol

''The fact is that flash memory is physically organized in blocks (or pages) of data, usually 128K or 256K large. Things get even worse from the fact that in order to change even one single byte, the entire page has to be first erased and then re-written with its contents again. In our example the time needed to change one byte of information is calculated the following way:''

Dear Robert -

Please allow me to restructure this question... Trying to understand how we may differ and have

advantages from other processes.

*Specifically, can claim 6 line (b) of patent 737 when marking bad segments under a read/write

block logical format size....salvage the balance of the erase block(array) , or would the whole

array be marked dead?

Respectfully,

Tim


Hi, Tim,

It's my understanding that the marking of defective memory segments is not
limited to the whole array.

Best regards,

````
Here-in-lies the discrepancy imvho.

''It is a simple trade-off between read/write performance and some RAM being used to cache the pages''

Amen in highlighting this -
''What this means is that information that is stored in a contiguous matter is more likely to be found in the cache than non-contiguous information.''

As for Sammies oneNAND - Remember we did Handheld Nor FIRST.
