The Raspberry Pi has two fixed chip select and chip enable outputs: Pin 24 is CE0, pin 26 is CE1. Use spi.open (0,0) when using the component connected to CE0, or spi.open (0,1) if the chip select output CE1 is used. The first number before the comma determines the SPI channel, in ours …

Address bit 8 being a 0 would enable chip select on one of the memories but not the other and address bit 8 being a 1 during the transaction would assert chip select on the other memory but not the first. Another situation is think about a 32 bit wide bus using 8 bit wide parts.
Web– /WE: write enable- when activated, values on data lines are written to specified address – /OE: output enable - data at specified location placed on data pins of memory chip, data lines connected to data bus using tristate outputs – /CS: chip select - selects a specific chip in an array of memory chips •Connection to HC12 -----
