READ_BL_PARTIAL
Defines whether partial block sizes can be used in block read commands.
●
WRITE_BLK_MISALIGN
Defines if the data block to be written by one command can be spread over more than one
physical block of the memory device. The size of the memory block is defined in
WRITE_BL_LEN.
READ_BLK_MISALIGN
Defines if the data block to be read by one command can be spread over more than one
physical block of the memory device. The size of the memory block is defined in
READ_BL_LEN.
DSR_IMP
This parameter allows to select the configurable driver stage on the device. If set, a driver
stage register (DSR) must be implemented also.
Table 41.
C_SIZE
This parameter is used to compute the NAND08GAH0A and NAND16GAH0D memory
density.
The memory capacity of the device is computed from the entries C_SIZE, C_SIZE_MULT
and READ_BL_LEN as follows:
Memory capacity = BLOCKNR * BLOCK_LEN, where:

●
Therefore, the maximal capacity which can be coded is 4096*512*2048 = 4 Gbytes.
NAND08GAH0A and NAND16GAH0D (densities ≤ 2 Gbytes, byte access mode):
–
–
WRITE_BLK_MISALIGN=0 signals that cross physical block boundaries are invalid.
WRITE_BLK_MISALIGN=1 signals that cross physical block boundaries are allowed.
READ_BLK_MISALIGN=0 signals that cross physical block boundaries are invalid.
READ_BLK_MISALIGN=1 signals that cross physical block boundaries are allowed.
BLOCKNR = (C_SIZE+1) * MULT
MULT = 2
BLOCK_LEN = 2
DSR_IMP
READ_BL_PARTIAL = ‘0’ means that only the 512-byte and the READ_BL_LEN
size can be used for block oriented data transfers.
READ_BL_PARTIAL = ‘1’ means that smaller blocks can be used as well. The
minimum block size will be equal to minimum addressable unit (one byte).
