Some SPI flash parts, such as W25Q64FV have a HOLD# signal on pin 7 instead of a RESET#. From the datasheet:

The /HOLD pin allows the device to be paused while it is actively selected. When /HOLD is brought low, while /CS is low, the DO pin will be at high impedance and signals on the DI and CLK pins will be ignored (don’t care). When /HOLD is brought high, device operation can resume.
