Hello,
I am using Flash memory S25HL512T for my application. In this I need an clarification in calculating the size of memory.
In the above image from the product datasheet, there are totally 256 sectors in which each sector size is 256kb, so totally 65536kb which is equal to 64Mb, but my Flash memory size is 512Mb. Please help me to find the correct calculation of memory size.
Thanks,
Vijay K S

Hello Vijay,
Your subject FLASH device is the S25HL512T (512Mb density, with 256 uniform sectors).
Each uniform sector is 256KBytes (256,000Bytes) in size.
Therefore, convert Bytes to bits: 256,000Bytes x 8bits = 2,048,000bits (per sector)
There are 256 uniform sectors, hence : 256 sectors x 2,048,000bits = 524,288,000bits (512Mb memory density)
With regards to your calculation, you are correct at 65,536KBytes (64MBytes, not Mb), but you will need to convert from Bytes to bits. Therefore, 65,536,000Bytes x 8bits = 524,288,000bits (512Mb memory density).
'B' = Bytes
'KB' = KiloBytes
'MB' = MegaBytes
'b' = bits
'Mb' = Megabits
'Gb' = Gigabits
Therefore, if your application requires a 3.0V, 512Mb memory density, then the S25HL512T
is the correct FLASH memory density to design into your application.
Hope this helps...
