SuperFlash Memory Products High Performance, Low Power Consumption and Superior Reliability What is SuperFlash Memory Cell Structure Comparison SuperFlash is an innovative, highly reliable and versatile type of NOR Flash memory invented by Silicon Storage Technology (SST). SuperFlash memory is much more exible and reliable than competing non-volatile memories. This technology Poly 2 Poly 1 utilizes a split-gate cell architecture which uses a robust thick-oxide process that requires fewer Source Drain Split Gate mask steps resulting in a lower-cost nonvolatile Thicker tunnel memory solution with excellent data retention and oxide reduces SuperFlash leakage higher reliability. improving data SuperFlash Advantages retention and reliability. Fast, xed program and erase times ~ 40 ms vs. more than a minute for 64 Mb Results in improved manufacturing ef ciency and lower costs Poly 2 No pre-programming or verify required prior to Poly 1 erase Results in signi cantly lower power Source Drain Stacked Gate consumption (Conventional Flash) Superior reliability 100K cycles and 100 years data retention Inherent small sector size 4 KB erase sector vs. 64 KB Results in faster re-write operations and Fast erase performance improves contributes to lowering overall power manufacturing ef ciency and lowers costs consumption SST38VF640X Competitor A Competitor B Parameter Parallel Flash 64 Mb 64 Mb 64 Mb Densities from 512 Kb to 64 Mb Typ Max Typ Max Typ Max Operating voltage: 1.8V, 3V and 5V Read 90 ns 90 ns 90 ns HW reset/Boot block/Erase suspend Page Read (Word in page 25 ns 25 ns 25 ns Security ID and page read/write on 64 Mb after initial access) Serial Flash Program 7 s 10 s 60 s 50 s Densities from 512 Kb through 64 Mb Write Buffer Programming 240 s 240 s 28 s 40 s (up to 16 words) (200 s)* (200 s)* Voltages available: 1.8V, 2.5V and 3.0V Single footprint package up to 32 Mb Erase Sector (4 KWord 18 ms 25 ms N/A N/A N/A N/A Full SPI protocol compatibility Erase Block (32 KWord) 18 ms 25 ms 0.5 sec 3.5 sec 0.5 sec Fast AAI programming mode Erase Full Chip 40 ms 50 ms 64 sec 128 sec 64 sec 128 sec *Must use external 12V supply to achieve numbers inside ( ).
