Each memory BANK contains the frame-image grayscale data of all the 64 lines. Each line comprises 16 48-bit-width memory units. Each memory unit contains the grayscale data of the corresponding R/G/B channels.

Depending on the number of scan lines set in SCAN_NUM (FC0 bit 21 to bit 16), the total number of memory units that must be written in one BANK is: 48 × the number of scan lines. For example, if the number of scan lines is set to 64, then 3072 (64 × 48 = 3072) memory units must be written during each frame period.

Figure 8-27 shows the detailed memory structure of the TLC6984 device.
