20100149881 | ADAPTIVE ERASE AND SOFT PROGRAMMING FOR MEMORY - An erase sequence of a non-volatile storage device includes an erase operation followed by a soft programming operation. The erase operation applies one or more erase pulses to the storage elements, e.g., via a substrate, until an erase verify level is satisfied. The number of erase pulses is tracked and recorded as an indicia of the number of programming-erase cycles which the storage device has experienced. The soft programming operation applies soft programming pulses to the storage elements until a soft programming verify level is satisfied. Based on the number of erase pulses, the soft programming operation time is shortened by skipping verify operations for a specific number of initial soft programming pulses which is a function of the number of erase pulses. Also, a characteristic of the soft programming operation can be optimized, such as starting amplitude, step size or pulse duration. | 2010-06-17 |

20100149883 | SEMICONDUCTOR DEVICE - In a semiconductor device having a data input buffer capable of inputting write data to each of memory units, the data input buffer is changed from an inactive state to an active state after the reception of instruction for a write operation effected on the memory unit. The data input buffer is a differential input buffer having interface specs based on SSTL, for example, which is brought to an active state by the turning on of a power switch to thereby cause a through current to flow and receives a signal therein while immediately following a small change in small-amplitude signal. Since the input buffer is brought to the active state only when the write operation's instruction for the memory unit is provided, the data input buffer is rendered inactive in advance, before the instruction for the write operation is provided, whereby wasteful power consumption is reduced.
