Why does this SRAM chip hashave more physical Bits thenbits than declared by the manufacturer?

Hi I noticed while scanning an SRAM chip 23K256the datasheet for a 23K256 It SRAM chip that it has 32768 bytebytes (+262Kbit). The Manufacturer)

The manufacturer clearly identifyidentifies this chip as 256Kbit... Reading

Reading through the datasheet it clearly says "32768 x 8" which confirms my scan result - but it doesn't sayssay what are those extra 6Kbit are for.

Anyone can shed some light on thosethis:

  1. Why 262 while its rated 256 and the actual documented maxmaximum address is 0x7FFF (32767)?
  2. Can I use this extra space? Is it safe?
  3. Can bits on the SRAM (or maybe bytes) get damaged over time?

Thanks
