Memory Blocks
The devices featureasymmetrically blocked archi-
tecture providing system memoryintegration. Both
M29W800AT and M29W800AB devices have an
array of 19 blocks, one Boot Block of 16 KBytes or
8 KWords, two Parameter Blocks of 8 KBytes or 4
KWords, one Main Block of 32 KBytes or 16
KWords and fifteen Main Blocks of 64 KBytes or
32 KWords. The M29W800AT has the Boot Block
at the top of the memory address space and the
M29W800AB locates theBoot Block startingat the
bottom. The memory maps are showed in Figure
5.
Each block can be erased separately, any combi-
nation of blocks can be specified for multi-block
erase or the entirechip maybe erased. The Erase
operations are managed automatically by the P/
E.C. The block erase operation can be suspended
in order to read from or program to any block not
being erased, and then resumed.
Block protection provides additional data security.
Each block can be separately protected or unpro-
tected against Program or Erase on programming
equipment. All previously protected blocks can be
temporarily unprotected in the application.
Organisation
The M29W800A is organised as 1M x8 or 512K
x16 bits selectable by the BYTE signal. When
BYTE is Low the Byte-wide x8 organisation is se-
lected and the address lines are DQ15A–1 and
A0-A18. The Data Input/Output signal DQ15A–1
acts as address line A–1 which selects the lower
or upper Byte of the memory word for output on
DQ0-DQ7, DQ8-DQ14remain at High impedance.
When BYTE isHigh the memory uses the address
inputs A0-A18 and the Data Input/Outputs DQ0-
DQ15. Memorycontrol isprovided by Chip Enable
E, Output Enable G and Write Enable W inputs.
A Reset/Block Temporary Unprotection RP tri-lev-
el input provides a hardware reset when pulled
Low, and when held High (at V
ID
) temporarily un-
protects blocks previously protected allowing them
to be programed and erased. Erase and Program
operations are controlled by an internal Program/
Erase Controller (P/E.C.). Status Register data
output on DQ7 provides a Data Polling signal, and
DQ6 and DQ2 provide Toggle signals to indicate
the state of the P/E.C operations. A Ready/Busy
RB output indicates the completion of the internal
algorithms.
