8-column block write (TMS5517x)
The 8-column block-write function allows up to 128 bits of data to be written simultaneously to one row of the
memory array. This function is implemented as 8 columns
×
8 DQs and repeated in two bytes. In this manner,
each of the two bytes can have up to eight consecutive columns written at a time with up to eight DQs per column
(see Figure 13).

Figure 13. 8-Column Block-Write Operation
Each byte has an 8-bit column mask to mask off any or all of the eight columns from being written with data.
Nonpersistent write-per-bit or persistent write-per-bit functions can be applied to the block-write operation to
provide write-masking options. Write data (color data) is provided by eight bits from the on-chip color register.
Bits 0
–
7 from the 16-bit write-mask register, bits 0
–
7 from the 16-bit column-mask register, and bits 0
–
7 from
the 16-bit color-data register configure the block write for the lower byte, while bits 8
–
15 control the upper byte
in a similar fashion (see Figure 14).
