Before getting into specific parts, a couple of articles on NAND and NOR based flash memory types:

Specific Memory Parts

Macronix International manufactures some 8Mbit FLASH NOR memory devices:

Microchip memory devices:

    An excerpt:
      16Mb 2.7-3.6V SPI Serial Flash
      
      Status: In Production
      Features:
      
          Serial Interface Architecture– SPI Compatible: Mode 0 and Mode 3
          Up to 50 MHz Clock Frequency
          Superior Reliability– Endurance: 100,000 Cycles (typical)– Greater than 100 years Data Retention
          Low Power Consumption:– Active Read Current: 10 mA (typical)– Standby Current: 5 µA (typical)
          Flexible Erase Capability– Uniform 4 KByte sectors– Uniform 32 KByte overlay blocks– Uniform 64 KByte overlay blocks
          Fast Erase and Byte-Program:– Chip-Erase Time: 35 ms (typical)– Sector-/Block-Erase Time: 18 ms (typical)– Byte-Program Time: 7 µs (typical)
      

A part alternate to the MX...8035, two parts by Microchip. On Microchip's site there is mention that the SST26 prefixed part is recommended over the SST25, but did not see mention of end-of-life or other obsolescence at their site. Following are 16Mbit (2 Mbyte) and an 8Mbit (1 Mbyte) NOR flash memory: ul
