Any very low power SPI flash?

Hi, i am developing a battery (CR2032) powered device that must log a few
sensors for a minimum of 3 months every minute but longer would be better.
The duty cycle is very low. In order to save the data i will be using an
SPI flash (16Mb). I was comparing at Atmel and SST (Microchip) and SST
seems to have the lowest current consumption device (max 15uA at standby)
but it is still a bit high compared to the microcontroller (MSP430 for
instance) and other sensors. Acceptable but high. Does any one knows any
other SPI flash with lower idle current and reasonble availability?
Second.. does any one knows if there is any problem on powering the flash
directly from the battery? Just asking becouse if there is a problem i will
have to use a boost converter (more costly and less power efficient).
