Data on TI flash cells has shown that the erase and program time walk-out is well beyond normal use conditions. Write Disturb During the program operation, high fields are placed not only on the bit being programmed, but on other bits along the same word line or bit line. If there are...
In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The...

A semiconductor device having an electrically erasable and programmable nonvolatile memory, for example, a rewritable nonvolatile memory including memory cells arranged in rows and columns and disposed to facilitate both flash erasure as well as selective erasure of individual units of plural memory cell...
2) Amaximum of 64 Flash sectors can be cycled 15,000 times. For all other sectors the limit is 1,000 cycles. 3) Thisparameter limits the number of subsequent programming operations within a physical sector. The drain disturb limit is applicable if wordline erase is used repeatedly. For nor...
The XC2764X is delivered with all Flash sectors erased and with no protection installed. The data retention time of the XC2764X’s Flash memory (i.e. the time after which stored data can still be retrieved) depends on the number of times the Flash memory has been ...
Data Retention - Read Disturb Write / Erase Endurance A read operation may disturb the data in memory. The data may change due to charge gain. Usually, bit errors occur on other pages in the block, not the page being read. After a large number of read cycles (between block ...
Not wanting to disturb Cyclops' marriage to Madelyne, Rachel kept her true relation to him secret. When she discovered that Scott would soon be the father of a child other than her, Rachel began to tap into the Phoenix Force and vowed to restore honor to her mother's name. Rachel ...
