J. Vanhoudt et al., HIMOS - A HIGH EFFICENCY FLASH E(2)PROM CELL FOR EMBEDDED MEMORY APPLICATIONS, I.E.E.E. transactions on electron devices, 40(12), 1993, pp. 2255-2263
This paper describes a novel Flash E(2)PROM device, which is programme
d with a highly efficient hot-electron injection mechanism. The High I
njection MOS (HIMOS) device combines a very high programming speed at
5-V-only operation with a low development entry cost, which renders it
a highly attractive concept for embedded memory applications. The HIM
OS concept exhibits complete soft-write immunity and the possibility o
f overerasure without causing any problem in a memory architecture. Fu
rthermore, it is shown that this device can also operate with a 3.3-V
voltage supply, which is of a major importance for the nest generation
s of submicron Flash E(2)PROM technologies.
