Saving a pin with 23LCV1024 on SPI mode

hello,

i received 23lcv1024 memory module, planning use temporary memory buffer in camera project. have working following setup on arduino uno:

arduino --> 23lcv1024
13 --> sck (pin 6)
12 --> (pin 2)
11 --> si (pin 5)
10 --> cs (pin 1)

here specs 23lcv1024: http://ww1.microchip.com/downloads/en/devicedoc/25156a.pdf

using spiram library updated 1024, able read , write data module. great!

here problem: out of pins. need use pins on uno camera module, including pin 10. leaves me 11, 12 , 13 communicate memory module.

since using single memory module, need chip select? there way of using spi module on 3 pins?

i appreciate on this. thanks!

yes, need chip select. pulling low tells chip new command being sent (read or write).

if tell more camera interface may find there way move pins io extender or similar.
