摘要： The present invention provides a flash memory including a memory cell, a current limiter and a program voltage generator. The memory cell is programmed in response to a program current and a program voltage. The current limiter reflects amount of the program current by a data-line signal, e.g., a data-line voltage. The program voltage generator generates and controls the program voltage in response to the data-line voltage, such that the program current can track to a constant reference current.

摘要： A flash memory cell includes a first conductive type substrate, a stacked gate structure, a first conductive type source/drain region, a metal silicide layer, an inter-layer dielectric layer and a contact plug. The first conductive type substrate has a second conductive type shallow well already formed thereon. The metal silicide layer is disposed within the first conductive type drain region. The contact plug is disposed within the inter-layer dielectric layer and electrically connected with the metal silicide layer in the first conductive type drain region to reduce resistance between the contact plug, the first conductive type drain region and the second conductive type shallow well and increase read-out speed of the flash memory.

摘要： A method for erasing a non-volatile memory is provided. The non-volatile memory includes a first conductive type substrate, a second conductive type well disposed in the first conductive type substrate, a first conductive type well disposed on the second conductive type well, and a memory cell disposed on the first conductive type substrate. The memory cell includes a charge trapping layer and a gate. The erasing method includes the following steps. A first voltage is applied to the gate, a second voltage is applied to the first conductive type substrate, and the second conductive type well is floating. The second voltage is large enough to induce a substrate hot hole effect. The holes are injected into the charge trapping layer by applying the first voltage.
