Initial issue.
Revised real-time map-out algorithm(refer to technical notes)
1. Changed device name
i. KM29U256T -> K9F5608U0M-YCB0
ii. KM29U256IT -> K9F5608U0M-YIB0
1. Changed tWP AC Timing
- If tCS is set less than 10ns, tWP must be minimum 35ns, otherwise
tWP may be minimum 25ns.
2. Changed Sequential Row Read operation
- The Sequential Read 1 and 2 operation is allowed only within a block
3. Changed invalid block(s) marking method prior to shipping
- The invalid block(s) information is written the 1st or 2nd page of the
invalid block(s) with 00h data
--->The invalid block(s) status is defined by the 6th byte in the spare
area. Samsung makes sure that either the 1st or 2nd page of every
invalid block has 00h data at the column address of 517.
4. Added a new card-type package : K9S5608U0M-MCB0
1. Changed Endurance : 1million -> 100K Program/Erase Cycles
1. Changed package name
: K9S5608U0M-MCB0 ->K9F5608U0M-MCB0(Micro Flash Card)
2. Changed invalid block(s) marking method prior to shipping
- The invalid block(s) status is defined by the 6th byte in the spare
area. Samsung makes sure that either the 1st or 2nd page of every
invalid block has
00h data
at the column address of 517.
--->The invalid block(s) status is defined by the 6th byte in the spare
area. Samsung makes sure that either the 1st or 2nd page of every
invalid block has
non-FFh
data at the column address of 517.
1. Removed Micro Flash Card
2. Changed SE pin description
- SE is recommended to coupled to GND or Vcc and should not be
toggled during reading or programming.

1. Explain how pointer operation works in detail.
Nov. 20th 2000
2. Renamed GND input (pin # 6) on behalf of SE (pin # 6)
- The SE input controls the access of the spare area. When SE is high,
the spare area is not accessible for reading or programming. SE is rec
ommended to be coupled to GND or Vcc and should not be toggled
during reading or programming.
=> Connect this input pin to GND or set to static low state unless the
sequential read mode excluding spare area is used.
3. Updated operation for tRST timing
- If reset command(FFh) is written at Ready state, the device goes into
Busy for maximum 5us.
