Abstract: Some embodiments include first bit lines coupled to a first junction bus and second bit lines coupled to a second junction bus. Such embodiments can also include a first network to discharge at least one of the first bit lines through the first junction bus and to discharge at least one of the second bit lines through the second junction bus. Such embodiments can further include a second network to couple a sense amplifier to at least one of the first junction bus and the second junction bus. Other embodiments are described.

Abstract: Bit lines of a memory device are arranged by an interleaving of even and odd bit lines and segregated into an even and odd bank. A discharge network discharges the banks alternately. A bit line selection network alternately connects the banks to a sense amplifier. The bank of odd bit lines is discharged just prior to a selection of the bank of even bit lines for reading and vice-versa. Interleaving even and odd bit lines in combination with alternating selection and discharge of banks reduces a cross coupling voltage. A discharge delay ensures that a sense amplifier does not detect any signal during a discharge phase. The discharge delay is much shorter than the cross coupling delay required with no discharge scheme present. Discharging complementary banks of bit lines plus reduced discharge delay ensures that along with a short access time, correct data are detected by the sense amplifier.

Abstract: A self-adaptive programming circuit for EEPROM is used to automatically tune an erase or write delay, providing an improved programming window. The programming circuit may also provide improvements in data retention for programmed memory cells. The invention can be applied more particularly in the field of EEPROM memories capable of page mode writing operations.

Abstract: An EEPROM memory circuit in which the loading of the column latches can be performed simultaneously with reading of the memory array. In this memory circuit, the data input connects directly to the column latches, leaving the bit lines open for memory reading by the sense amplifiers, which is connected directly to the bit lines. Two separate Y address decoders, one feeding into the column latches and the other into the bit line select circuit, provide column latch and bit line selection respectively.
