C6745 16bit SDRAM connection Confirmation

In Datasheet of C6745 page 93,   Table 6-24 EMIFB Supported SDRAM Configurations, we can see that  when you use 16bits SDRAM , it needs 2pcs.

It  doesn't mention it can support 1pcs 16bits SDRAM in the table .

But  in Figure 6-19. EMIFB to 2M × 16 × 4 bank SDRAM Interface ,  it shows 1pcs 16bits SDRAM  connected to C6745.  

My question is as following :  

Can I use only 1pcs 16bits SDRAM (Such as EM639165TS-6G) for DSP C6745 ?   

Thanks !
