I noticed while scanning the datasheet for a 23K256 SRAM chip that it has 32768 bytes (+262Kbit.)
The manufacturer clearly identifies this chip as 256Kbit.
Reading through the datasheet it clearly says "32768 x 8" which confirms my scan result - but it doesn't say what those extra 6Kbit are for.
Anyone can shed some light on this:
- Why 262 while its rated 256 and the actual documented maximum address is 0x7FFF (32767)?
- Can I use this extra space? Is it safe?
- Can bits on the SRAM (or maybe bytes) get damaged over time?
