256Mx16 4Gb DDR3 SDRAM one bank?

Hello,

 

Stupid question, can I make an I.MX7 work with one bank of 256Mx16 4Gb DDR3 SDRAM or do I need two banks to connect all data pins on the chip?

 

 

 

 

Data Strobe: output with read data, input with write data. Edge-aligned with read data, centered in write data. For the x16, DQSL corresponds to the data on DQL0-DQL7; DQSU corresponds to the data on DQU0-DQU7. The data strobes DQS, DQSL, and DQSU are paired with differential signals DQS#, DQSL#, and DQSU#, respectively, to provide differential pair signaling to the system during reads and writes. DDR3 SDRAM supports differential data strobe only and does not support single-ended.

 

Can I connect DQL0-DQL7 to ADDR0-7 and DQU0-DQU7 to to ADDR8-15 ? 

And then conect the differential signals of the datastrobes DQS, DQSL, and DQSU & DQS#, DQSL#, and DQSU#

 

Thanks

 

Herman
